Red hair
Red hair (or ginger hair) occurs naturally in 1–2% of the human population. It occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations. Red hair appears most commonly in people with two copies of a recessive allele on chromosome 16 which produces an altered version of the MC1R protein. Red hair varies in hues from a deep burgundy or bright copper (reddish-brown or auburn) through to burnt orange or red-orange and strawberry blond. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin.
Human hair color
Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. The darker a person's natural hair color is, the more individual hair follicles they have on their scalp. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Particular hair colors are associated with ethnic groups. Gray or white hair is associated with age. The Fischer–Saller scale, named after Eugen Fischer and , is used in physical anthropology and medicine to determine the shades of hair color.
Human overpopulation
Human overpopulation (or population overshoot) occurs when the ecological footprint of a human population in a specific geographical location exceeds the carrying capacity of the place occupied by that group. Overpopulation can further be viewed, in a long term perspective, as existing if a population cannot be maintained given the rapid depletion of non-renewable resources or given the degradation of the capacity of the environment to give support to the population. Changes in lifestyle could reverse overpopulated status without a large population reduction. The term "human overpopulation" refers to the relationship between the entire human population and its environment: the Earth, or to smaller geographical areas such as countries.
Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.
Human
Modern humans ("Homo sapiens", ssp. "Homo sapiens sapiens") are the only extant members of the subtribe Hominina, a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; and a general trend toward larger, more complex brains and societies. Early hominins—particularly the australopithecines, whose brains and anatomy are in many ways more similar to ancestral non-human apes—are less often referred to as "human" than hominins of the genus "Homo". Several of these hominins used fire, occupied much of Eurasia, and gave rise to anatomically modern "Homo sapiens" in Africa about 315,000 years ago.
Blond
Blond (male), blonde (female), or fair hair, is a hair color characterized by low levels of the dark pigment eumelanin. The resultant visible hue depends on various factors, but always has some sort of yellowish color. The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish "strawberry" blond or golden-brownish ("sandy") blond colors (the latter with more eumelanin). On the Fischer–Saller scale, blond color ranges from A (light blond) to O (dark blond). The word "blond" is first documented in English in 1481 and derives from Old French "blund, blont", meaning "a colour midway between golden and light chestnut".
Race (human categorization)
Race is a concept used in the categorization of humans into groups, called races or racial groups, based on combinations of shared physical traits, ancestry, genetics, and social or cultural traits. Although such groupings lack a firm basis in modern biology, they continue to have a strong influence over contemporary social relations. First used to refer to speakers of a common language and then to denote national affiliations, by the 17th century race began to refer to physical (phenotypical) traits. The term was often used in a general biological taxonomic sense, starting from the 19th century, to denote genetically differentiated human populations defined by phenotype.

White Latin Americans
White Latin Americans or European Latin Americans are Latin Americans who are considered white, typically due to European, or in some cases Levantine, descent. Latin American countries have often encouraged miscegenation, and even a small amount of European ancestry could entail significant upwards social mobility. People descended from European settlers who arrived in the Americas during the colonial and post-independence periods can be found throughout Latin America. Most of the earliest settlers were Spanish and Portuguese; after independence, the most numerous immigrants have been Spanish and Italians, followed by Germans, Levantine Semites, Poles, Irish, British, French, Russians, Belgians, Dutch, Scandinavians, Ukrainians, Hungarians, Croats, Swiss, Greeks, and other Europeans.
White Brazilians
White Brazilians ( ) refers to Brazilian citizens of European or Levantine descent. According to the 2010 Census, they totaled 91,051,646 people, and made up 47.73% of the Brazilian population. The main ancestry of white Brazilians is Portuguese, followed by Italian, Spanish, German, and other German-speaking nationalities (Austrian, Swiss, Luxembourger and Volga German) Slavic (Polish, Ukrainian, Russian etc), Levantine, Dutch, French and Baltic. The white Brazilian population is spread throughout the national territory, but its highest percentage is found in the three southernmost states, where 79.8% of the population has European or Caucasian phenotype, whereas the Southeast region has the largest absolute numbers.
Afro-Brazilians
Afro-Brazilians (; ) is a term used in the 21st century by some in Brazil to refer to Brazilian people with African ancestry. The term does not have widespread use in Brazil, where social constructs and classifications have been based on appearance. People with noticeable African features and skin color are generally referred to (and they identify) as "negro" or "preto" ("black"). Many members of another group of people, multiracial Brazilians, or "pardos", also have a range of degree of African ancestry. Preto and pardo are among five color categories used by the Brazilian Census, along with "branco" ("white"), "amarelo" ("yellow", East Asian) and "indígena" (Amerindian).
Mexicans of European descent
European Mexicans are Mexican citizens of complete or predominant European descent. While the Mexican government periodically conducts racial censuses for "Indigenous Mexicans" and "Afro-Mexicans" it has not conducted a census for European Mexicans for nearly a century. Estimates of this ethnic group as a segment of the country's population range from 9% and 20% according to "The World Factbook" and Encyclopædia Britannica to as high as 47% according to the ENADIS 2010 (National Survey About Discrimination), conducted by the CONAPRED (National Council to Prevent Discrimination) as a mean to address the problems of racism that Mexicans of mainly Indigenous or African ancestry suffer at hands of a society that favors light skinned, European looking Mexicans.
Genetic studies on Jews
Genetic studies on Jews are part of the population genetics discipline and are used to better understand the chronology of migration provided by research in other fields, such as history, archaeology, linguistics, and paleontology. These studies investigate the origins of various Jewish populations today. In particular, they investigate whether there is a common genetic heritage among various Jewish populations. Studies of autosomal DNA, which look at the entire DNA mixture, show that Jewish populations have tended to form relatively closely related groups in independent communities, with most in a community sharing significant ancestry and up to 75% Levantine genes.
Race and ethnicity in Brazil
Brazilian society is made up of a confluence of people of several different origins, from the original Native Brazilians, with the influence of Portuguese colonizers, Black African, and European, Arab, and Japanese immigration. Other significant groups include Koreans, Chinese, Paraguayans, and Bolivians. Brazil has seen greater racial equality over time. According to a recent review study, "There has been major, albeit uneven, progress in these terms since slavery, which has unfortunately not wholly translated into equality of income: only in 2010 did the black-to-white income ratio eclipsed its 1960 level, although it appears to be at an all-time high.
White people
White people is a racial classification specifier, used for people of Caucasian ancestry, with the exact implications dependent on context. The usage of "white people" or a "white race" for a large group of (mainly European) populations, defined besides other characteristics by their light skin and contrasting with "black people", Native Americans, "colored" or "persons of color" originated in the 17th century. It was only during the 18th century, that this floating category was transformed in a quasi-scientific system of race and skin color relations. The concept of a homogeneous white race did not achieve universal acceptance in Europe.

Equine coat color genetics
Equine coat color genetics determine a horse's coat color. There are many different coat colors possible, but all colors are produced by the action of only a few genes. The combination of the extension and agouti loci determine the base coat of a horse.Bay is the original "wild type" color of horses. Ancient remains of horses were tested to be of bay base coat color. The Dun test was not available at the time, but those horses were also dun. (EE AA DD)  Red horses were created with a modification of the extension locus. Dominant extension mutated into a recessive form. When the horse is homozygous for recessive extension (or ee), the horse's base coat will be red.
Dominance (genetics)
Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive. For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics. Often the dominant allele codes for a functional protein whereas the recessive allele does not. A classic example of dominance is the inheritance of seed shape in peas.
Seal brown (horse)
Seal brown is a hair coat color of horses characterized by a near-black body color; with black points, the mane, tail and legs; but also reddish or tan areas around the eyes, muzzle, behind the elbow and in front of the stifle. The term is not to be confused with "brown", which is used by some breed registries to refer to either a seal brown horse or to a dark bay without the additional characteristics of seal brown genetics. Like bay, the seal brown color is produced by the Agouti ("A") gene acting upon a genetically black base coat, suppressing the black into point coloration and allowing the underlying reddish or brownish color to appear.
Labrador Retriever coat colour genetics
The genetic basis of coat colour in the Labrador Retriever (a highly popular breed of dog) has been studied in detail, and found to depend on several distinct genes. The interplay between these genes is broadly used as an example of epistasis. Labrador Retrievers are a popular breed of dog in many countries. There are three recognised colours, black, chocolate, and yellow, that result from the interplay among genes that direct production and expression of two pigments, eumelanin and pheomelanin, in the fur and skin of the dog. The recognized colours are due to two genes, while a third gene affects the range of colouration observed within the yellow Labrador.
Melanocortin 1 receptor
The melanocortin 1 receptor (MC1R), also known as melanocyte-stimulating hormone receptor (MSHR), melanin-activating peptide receptor, or melanotropin receptor, is a G protein–coupled receptor that binds to a class of pituitary peptide hormones known as the melanocortins, which include adrenocorticotropic hormone (ACTH) and the different forms of melanocyte-stimulating hormone (MSH). MC1R is one of the key proteins involved in regulating mammalian skin and hair color. It is located on the plasma membrane of specialized cells known as melanocytes, which produce the pigment melanin through the process of melanogenesis.
Zygosity
Zygosity is the degree of similarity of the alleles for a trait in an organism. Most eukaryotes have two matching sets of chromosomes; that is, they are diploid. Diploid organisms have the same loci on each of their two sets of homologous chromosomes except that the sequences at these loci may differ between the two chromosomes in a matching pair and that a few chromosomes may be mismatched as part of a chromosomal sex-determination system. If both alleles of a diploid organism are the same, the organism is homozygous at that locus. If they are different, the organism is heterozygous at that locus.

No they don't, But here is a simpler explanation, it's as a result  high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin.

Brown
Brown is a composite color. In the CMYK color model used in printing or painting, brown is made by combining red, black, and yellow, or red, yellow, and blue. In the RGB color model used to project colors onto television screens and computer monitors, brown is made by combining red and green, in specific proportions. The brown color is seen widely in nature, in wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; the color is most often associated with plainness, the rustic, feces, and poverty.

Brown hair is the second most common human hair color, after black hair. It varies from light brown to almost black hair. It is characterized by higher levels of the dark pigment eumelanin and lower levels of the pale pigment pheomelanin. Its strands are thicker than those of fair hair but not as much as those of red hair. People with brown hair are often referred to as brunette, which in French is the feminine form of "brunet," the diminutive of "brun" (brown, brown-haired or dark-haired). Brown hair is common among populations in the Western world, especially among those from Central Europe, Southeastern Europe, Eastern Europe, Southern Europe, Southern Cone, the United States, and also some populations in the Greater Middle East where it transitions smoothly into black hair.
