Twin study
Twin studies reveal the importance of environmental and genetic influences for traits, phenotypes, and disorders. Twin research is considered a key tool in behavioral genetics and in content fields, from biology to psychology. Twin studies are part of the broader methodology used in behavior genetics, which uses all data that are genetically informative – siblings studies, adoption studies, pedigree, etc. These studies have been used to track traits ranging from personal behavior to the presentation of severe mental illnesses such as schizophrenia. Twins are a valuable source for observation because they allow the study of environmental influence and varying genetic makeup: "identical" or monozygotic (MZ) twins share nearly 100% of their genes, which means that most differences between the twins (such as height, susceptibility to boredom, intelligence, depression, etc.)
Twin
Twins are two offspring produced by the same pregnancy. Twins can be either "monozygotic" ("identical"), meaning that they develop from one zygote, which splits and forms two embryos, or "dizygotic" ("fraternal"), meaning that they develop from two different eggs. In fraternal twins, each twin is fertilized by its own sperm cell. In contrast, a fetus that develops alone in the womb is called a "singleton", and the general term for one offspring of a multiple birth is "multiple". Non-related look-alikes whose resemblance parallels that of twins are referred to as doppelgangers. The human twin birth rate in the United States, rose 76% from 1980 through 2009, from 18.9 to 33.3 per 1,000 births.
Rybka Twins
Teagan Rybka and Sam Rybka (born 22 June, 1995), known as the Rybka Twins, are fraternal twin Australian YouTubers, actresses and singers who are the third place semi-finalists on series 7 of "Australia's Got Talent" in 2012-13. Teagan and Sam are fraternal twin sisters born in Perth, Western Australia on 22 June, 1995. Teagan is the older one, and Sam is the younger one. They have three older half brothers. Father Rybka died unexpectedly in late September 2017 during "Draw My Life," after "Who's the better twin? ", their 73rd video before Zayn becomes a "full white". The Rybka twins started going on "Australia's Got Talent" in late 2012 to early 2013 for series 7 until they placed third place in the semi-finals as acrobats, contortionists, dancers, and yoga (health & fitness) models.
Irving Gottesman
Irving Isadore Gottesman (December 29, 1930 – June 29, 2016) was an American professor of psychology who devoted most of his career to the study of the genetics of schizophrenia. He wrote 17 books and more than 290 other publications, mostly on schizophrenia and behavioral genetics, and created the first academic program on behavioral genetics in the United States. He won awards such as the Hofheimer Prize for Research, the highest award from the American Psychiatric Association for psychiatric research. Lastly, Gottesman was a professor in the psychology department at the University of Minnesota, where he received his Ph.D.  A native of Ohio, Gottesman studied psychology for his undergraduate and graduate degrees, became a faculty member at various universities, and spent most of his career at the University of Virginia and the University of Minnesota.
List of Kim Possible characters
This is a list of characters appearing in the animated series "Kim Possible". Kimberly Ann "Kim" Possible is a crime fighter and high school cheerleading captain who saves the world on a regular basis while dealing with the normal challenges of being a teenager, such as winning cheer competitions, turning in her homework on time, and maintaining a love life. Her name is a play on the word "impossible." Kim has known Ron Stoppable, her sidekick for most missions, since preschool. She has also completed missions with Wade, Monique, her brothers, and even her mother. In season four, Kim and Ron end up developing romantic feelings for each other and begin dating during their senior year.
Twin registry
A twin registry is a database of information about both identical twins and fraternal twins, which is often maintained by an academic institution, such as a university, or by other research institutions. The use of twins can improve the statistical power of a genetic study by reducing the amount of genetic and/or environmental variability. "Identical twins" (monozygotic (MZ) twins) share virtually all their genes with each other, and "fraternal twins" (dizygotic (DZ) twins), on average, share about 50% of their genes with each other (about the same amount of sharing as non-twin siblings). Both types of twin pairs in twin registries almost always share similar prenatal and early childhood environments as well.
List of The Brittas Empire characters
This is a list of characters for the 1990s BBC British Television sitcom "The Brittas Empire", a British television sitcom that aired on BBC 1 in the 1990s. Gordon Wellesley Brittas GM (born 1958) is the Manager of the ill-fated Whitbury Leisure Centre. Brittas is extremely dedicated to his job and cares dearly for everyone around him, including his unstable wife Helen. He has grand ambitions of making the world a better place, and aims to fulfill his dream of bringing people together through sport. Despite his noble and well-meant intentions, however, Brittas' management only ever causes disaster and chaos, resulting in pathetically low attendance rates, catastrophic fires, floods and even customer deaths on several occasions.

Because they are fraternal twins, their resemblance is no more or less than sibling. However, they have a great bond.

Sibling
A sibling is one of two or more individuals having one or both parents in common. A full sibling is a first-degree relative. A male sibling is a brother, and a female sibling is a sister. In most societies throughout the world, siblings often grow up together, thereby facilitating the development of strong emotional bonds. The emotional bond between siblings is often complicated and is influenced by factors such as parental treatment, birth order, personality, and personal experiences outside the family. However, there are cases where siblings grow up in separate homes, in different environments.

Helen L. Koch
Helen Lois Koch (August 26, 1895 – July 14, 1977) was an American developmental psychologist and a faculty member at the University of Texas at Austin and the University of Chicago. Koch developed nursery school teacher training programs during World War II and she researched the differences between sets of fraternal twins, identical twins and non-twin siblings. A graduate of the University of Chicago, Koch was credited with research work that improved the accuracy of investigations into sibling order. She was the co-winner of the first G. Stanley Hall Award for Distinguished Contribution to Developmental Psychology.
Nature versus nurture
The nature versus nurture debate is about whether human behaviour is determined by the environment, either prenatal or during a person's life, or by a person's genes. The alliterative expression "nature and nurture" in English has been in use since at least the Elizabethan period and goes back to medieval French. The combination of the two concepts as complementary is ancient (Greek: ). Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors. Nurture is generally taken as the influence of external factors after conception e.g. the product of exposure, experience and learning on an individual.
Biology and sexual orientation
The relationship between biology and sexual orientation is a subject of research. A simple and singular determinant for sexual orientation has not been conclusively demonstrated; various studies point to different, even conflicting positions, but scientists hypothesize that a combination of genetic, hormonal, and social factors determine sexual orientation. Biological theories for explaining the causes of sexual orientation are favored by experts and involve a complex interplay of genetic factors, the early uterine environment and brain structure. These factors, which may be related to the development of a heterosexual, homosexual, bisexual or asexual orientation, include genes, prenatal hormones, and brain structure.

Is it similar to the bond of identical twins?
0_Wizard
I think their bond is probably similar. Their behavior and mannerisms are very alike. Studies have shown this to be true as well.
These studies have been used to track traits ranging from personal behavior to the presentation of severe mental illnesses such as schizophrenia.

List of recurring The Simpsons characters
"The Simpsons" includes a large array of supporting characters: co-workers, teachers, family friends, extended relatives, townspeople, local celebrities, fictional characters within the show, and even animals. The writers originally intended many of these characters as one-time jokes or for fulfilling needed functions in the town. A number of them have gained expanded roles and have subsequently starred in their own episodes. According to the creator of "The Simpsons", Matt Groening, the show adopted the concept of a large supporting cast from the Canadian sketch comedy show "Second City Television".
List of Madagascar (franchise) characters
This is a list of characters that have appeared in the "Madagascar" films, the television series "The Penguins of Madagascar", and the Netflix series "All Hail King Julien". Tom McGrath explained in an interview that the intention of "Madagascar" was not to take a political stance on whether "zoos are bad and the wild is better, or that the wild is bad," but to show "the most extreme 'fish out of water' story that [they] could do". McGrath stated "the basic irony to the story is that, you think animals do belong in the wild, but if they're so accustomed to civility, they wouldn't know where food even came from," and the animals were meant to "love the zoo and to love where they are because they've got" "right off Fifth Avenue".
Self-disclosure
Self-disclosure is a process of communication by which one person reveals information about himself or herself to another. The information can be descriptive or evaluative, and can include thoughts, feelings, aspirations, goals, failures, successes, fears, and dreams, as well as one's likes, dislikes, and favorites. Social penetration theory posits that there are two dimensions to self-disclosure: breadth and depth. Both are crucial in developing a fully intimate relationship. The range of topics discussed by two individuals is the breadth of disclosure. The degree to which the information revealed is private or personal is the depth of that disclosure.
Belongingness
Belongingness is the human emotional need to be an accepted member of a group. Whether it is family, friends, co-workers, a religion, or something else, people tend to have an 'inherent' desire to belong and be an important part of something greater than themselves. This implies a relationship that is greater than simple acquaintance or familiarity. The need to belong is the need to give and receive attention to and from others. Belonging is a strong and inevitable feeling that exists in human nature. To belong or not to belong can occur due to choices of one's self, or the choices of others. Not everyone has the same life and interests, hence not everyone belongs to the same thing or person.

He was born in Denver, Colorado to his parents William Winger and Doreen Winger née Fitzgerald.
List of Warriors characters
The "Warriors" novel series is written by Erin Hunter. Due to the large number of characters present in the novel series, this list is divided by Clan, e.g., all characters in ThunderClan are listed together. Each cat has a prefix. Eg: Dawn, Violet etc. As a young kit they will have -kit at the end of their name. Eg: Dawnkit Violetkit. When they are an apprentice -paw will be at the end of their name. Eg: Dawnpaw Violetpaw. When that cat is a warrior or medicine cat they will have a suffix. Eg: -fur -pelt -cloud -flame -wing -song etc. Eg: Dawnsong Violetflame. That is if they are in one of the clans like ThunderClan, RiverClan, WindClan, ShadowClan, Skyclan.
Well-being contributing factors
Well-being is a much-studied topic in psychology, especially positive psychology. Related concepts are eudaimonia, happiness, flourishing, quality of life, contentment, and meaningful life. Central theories are Diener's tripartite model of subjective well-being, Ryff's Six-factor Model of Psychological Well-being, Corey Keyes' work on flourishing, and Seligmann's contributions to positive psychology and his theories on "authentic happiness" and P.E.R.M.A. Positive psychology is concerned with eudaimonia, "the good life" or flourishing, living according to what holds the greatest value in life – the factors that contribute the most to a well-lived and fulfilling life.

Do they have the same favorite foods?

That's a great question. I don't think so! I just read that in N. America, the rate of a twin birth is 9-16 twin sets per 1,000 births.  That seems like a lot!
North America and Europe have intermediate rates of 9 to 16 twin sets per 1,000 live births.

Twin
Twins are two offspring produced by the same pregnancy. Twins can be either "monozygotic" ("identical"), meaning that they develop from one zygote, which splits and forms two embryos, or "dizygotic" ("fraternal"), meaning that they develop from two different eggs. In fraternal twins, each twin is fertilized by its own sperm cell. In contrast, a fetus that develops alone in the womb is called a "singleton", and the general term for one offspring of a multiple birth is "multiple". Non-related look-alikes whose resemblance parallels that of twins are referred to as doppelgangers. The human twin birth rate in the United States, rose 76% from 1980 through 2009, from 18.9 to 33.3 per 1,000 births.
Infant mortality
Infant mortality refers to deaths of young children, typically those less than one year of age. It is measured by the infant mortality rate (IMR), which is the number of deaths of children under one year of age per 1000 live births. The Under-Five Mortality Rate is also an important statistic, considering the Infant Mortality Rate focuses only on children under one year of age. Premature birth is the biggest contributor to the IMR. Other leading causes of infant mortality are birth asphyxia, pneumonia, term birth complications such as abnormal presentation of the foetus umbilical cord prolapse, or prolonged labor, neonatal infection, diarrhea, malaria, measles and malnutrition.
Birth rate
The birth rate (technically, births/populatiohoes is the total number of live births per 1,000 of a population in a year or period. The rate of births in a population is calculated in several ways: live births from a universal registration system for births, deaths, and marriages; population counts from a census, and estimation through specialized demographic techniques. The birth rate (along with mortality and migration rate) are used to calculate population growth. The "crude birth rate" is the number of live births per year per 1,000 midyear population Another term used interchangeably with "birth rate" is "natality".
Group B streptococcal infection
Group B streptococcus infection, also known as Group B streptococcal disease, is the infection caused by the bacterium "Streptococcus agalactiae" ("S. agalactiae") (also known as group B streptococcus or GBS). Group B streptococcal infection can cause serious illness and sometimes death, especially in newborns, the elderly, and people with compromised immune systems. GBS was recognized as a pathogen in cattle by Edmond Nocard and Mollereau in the late 1880s, but its significance as a human pathogen was not discovered before 1938, when Fry described three fatal cases of puerperal infections caused by GBS.
Multiple birth
A multiple birth is the culmination of one multiple pregnancy, wherein the mother delivers two or more offspring. A term most applicable to placental species, multiple births occur in most kinds of mammals, with varying frequencies. Such births are often named according to the number of offspring, as in "twins" and "triplets". In non-humans, the whole group may also be referred to as a "litter", and multiple births may be more common than single births. Multiple births in humans are the exception, and can be exceptionally rare in the largest mammals. Each single fertilized egg (zygote) may produce a single embryo, or it may split into two or more embryos, each carrying the same genetic material.
Brownsville, Brooklyn
Brownsville is a residential neighborhood located in eastern Brooklyn in New York City. The area that comprises Brownsville has 58,300 residents as of the 2010 United States Census. Part of Brooklyn Community Board 16, Brownsville is generally considered part of greater East New York, though it is not actually a part of East New York itself. The neighborhood's boundaries are unclear, but it is generally bordered by Crown Heights and Weeksville to the northwest; Bushwick and Cypress Hills to the north; New Lots to the east; Canarsie to the south; and East Flatbush to the west. Founded in its current incarnation in 1858, it has been characterized as a slum through most of its existence.
Cleft palate incidence by population
Cleft lip and/or palate is a congenital abnormality that is seen frequently around the world. On average, about 1 in every 500-750 live births result in a cleft (Hardin-Jones, Karnell, & Peterson-Falzone, 2001). Furthermore, in the U.S., the prevalence for cleft lip with or without cleft palate (CL +/- P) is 2.2 to 11.7 per 10,000 births. Cleft palate alone (CP) results in a prevalence rate of 5.5 to 6.6 per 10,000 births (Forrester & Merz, 2004). Cleft of the lip, palate, or both is one of the most common congenital abnormalities and has a birth prevalence rate ranging from 1/1000 to 2.69/1000 amongst different parts of the world (McLeod, Saeed, & Arana- Urioste, 2004).
