My father-in-law is a fraternal twin. I find the relationship between twins fascinating.
In fraternal twins, each twin is fertilized by its own sperm cell.

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

Me too.  Is there a strong resemblance?
