Caucasian people have the most variety in skin and eye color?

How come white people are the only people who have a variety in hair and eye color? Red hair, blonde, brown, strawberry, golden, dirty blonde, black. Eye: green, blue, grey, hazel, brown etc.





I never see Chinese, spanish, black, or Indians having these varieties. They always only have black hair and brown eyes... the only time it occurs is if they are half white or something like that.... how come?





Scientific explanations would be appreciated.Caucasian people have the most variety in skin and eye color?
There are some others besides Caucasians with color variety but it is mostly due to to having mixed with a Caucasian not always the case though.





I forget the groups name but there is a small and secluded group of black people that had straight dirty blond hair, which looked so bizarre and awesome I think.





To make it simple Caucasians have more recessive traits as well as less natural melanin(which darkens the skin or eyes to protect from the suns radiation and thus more lighter colors possible.





Also the founders effect and genetic drift help this out more (founders effect and genetic drift being a loss of variation in a small population with certain genes being expressed more, like the Icelanders and red hair) , so when Europeans started mixing more often, all these specialized strains in these small populations were now being found in what we call Caucasians.Caucasian people have the most variety in skin and eye color?
I think Caucasians have more recessive genes. Thus, the many variations in eye colour. Eg. 2 brown eyed (non-white) parents may not have enough dominant 'brown eye genes' to make a brown eyed child. Instead, they'll have a blue eyed one.





Caucasian's hair colour is derived from the environment they live in. If they lived in India they would have black, brown hair too. In fact, Indians are considered Caucasian as well (they have White features, deep set eyes, etc...)





But because the environment is less sunny, the hair becomes lighter. Eg. Caucasians in Spain (hispanics) have darker hair than Caucasians in Russia.





Not very scientific I'm afraid haha.
Hmmmmm.......hmmmmmm. Not always at my school are some black people who are from Carribean, they're r brothers and they both have this beautiful hazel blue eyes.


Also, my best friend who is from Angola her dad have this mixture of red, white and blond hair and he never in his life dyed his hair. He is black black black.


Also I know that people from one part of African have red red hair and they even don't dye them.
Tru that they are USUALLY the ones with coloured eyes not always though. it's because they have a diverse gene pool because most of them are mixed and don't have a lot of melanin. BUT brown people(not black) have the most diverse skin tone from white to black.





BTw to MCConally: if your answer is true, why do I have green eyes when I am not mixed with white? and I know a lot of my persian brothers and sisters have all kinds of hair colours including blonde, brown even red! Ever heard of the true aryans from persia?
I think this is about the environment white people live in. People in the north have lighter skin and hair. I don't know if animals and people are alike in this but wolves in the north have blue eyes but I think lions and hyenas in africa and yellowish to brown to dark black eyes.
my idea is that ';caucasian'; referes to many many people groups. someone who is from germany tends to be pretty distinc from someone who is spanish or who is russian. i think the variety comes from the fact that there are a lto of diffderent ';races'; that come together under the caucasian label.
This boy I know has green eyes, he's fully black, no contacts my little cousin is light skinned with green eyes, he's fully black and he's a toddler so obviously no contacts. Black people can have a variety of things too, so can other races.
Well I can't outdo Clyde N in scientific explanation. But I personally know black people with hazel, Gray, or greenish eyes. And yes both there parents were black. I have a little cousin with dirty blond hair and she is completely black.
True, and it is also true that blacks are the only race with the most varieties of skin color, from white to black.
It might be because people in Europe live in so many different places,and maybe when they mix with other Europeans or someone of a different ethnicity they get a different colour?
I think you meant hair and eye color, not skin.





And the scientific explanation is recessive genes.
Spanish people? Excuse me but the people of Spain are ';White'; and do have light skin and colored hair/eyes.





You better not be calling Latin-Americans Spanish!!!
Pfttttttttttt.


hahahahaha...
Eye color is a polygenic trait and is determined by the amount and type of pigments in the eye's iris. Humans and animals have many phenotypic variations in eye color.In humans, these variations in color are attributed to varying ratios of eumelanin produced by melanocytes in the iris.





Three main elements within the iris contribute to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma.In eyes of all colors, the iris pigment epithelium contains the black pigment, eumelanin. Color variations among different irises are typically attributed to the melanin content within the iris stroma.The density of cells within the stroma affects how much light is absorbed by the underlying pigment epithelium.





Eye colors can range from most common color, brown, to least common, gray. Rare genetic mutations can even lead to unusual eye colors: black, red, and violet. Eye color is an inherited trait influenced by more than one gene. These genes are being sought using associations to small changes in the genes themselves and in neighboring genes. These changes are known as single nucleotide polymorphisms or SNPs. The actual number of genes that contribute to eye color is unknown at present, but there are a few likely candidates.





The gene OCA2 (OMIM: 203200), when in a variant form the gene causes the pink eye color and hypopigmentation common in human albinism, (the name of the gene is derived from the disorder it causes, oculocutaneous albinism type II). Different SNPs within OCA2 are strongly associated with brown and green eyes as well as variations in freckling, mole counts, hair and skin tone. The polymorphisms may be in an OCA2 regulatory sequence, where they may influence the expression of the gene product, which in turn affects pigmentation. A specific mutation within the HERC2 gene, a gene that regulates OCA2 expression, is partly responsible for blue eyes.Other genes implicated in eye color variation are: SLC24A4, TYR .





Blue eyes with a brown spot, green eyes and gray eyes are caused by an entirely different part of the genome. As Eiberg said: ';The SNP rs12913832 [of theHerc2 gene] is found to be associated with the brown and blue eye color, but this single DNA variation cannot explain all the brown eye color variation from dark brown over hazel to blue eyes with brown spots';.





Eye color usually stabilizes when an infant is around 6 months old.





The perception of color depends upon various factors. These are the same eyes; however, depending on the light and surrounding hues, the eye color can appear quite different.Iris color can provide a large amount of information about an individual and a classification of various colors may be useful in documenting pathological changes or determining how a person may respond to various ocular pharmaceuticals. Various classification systems have ranged from a basic


';light'; or ';dark'; description to detailed gradings employing photographic standards for comparison. Others have attempted to set objective standards of color comparison.





As the perception of color is dependent on viewing conditions (e. g. the amount and type of illumination, as well as the hue of the surrounding environment), so is the perception of eye color.





Eye color exists on a continuum from the darkest shades of brown to the lightest shades of blue. Seeing the need for a standardized classification system that was simple, yet detailed enough for research purposes, developed a graded one based on the predominant iris color and the amount of brown or yellow pigment present. There are 3 true colors in the eyes that determine the outward appearance; brown, yellow, and blue. How much of each color you have determines the appearance of the eye color. The color of the eyes in turn depends on how much of these colors are present. For example, green eyes have yellow and some blue, making them appear green. Brown eyes appear brown because most of the eye contains the brown color. The above is true for the species Homo sapiens.Although rare in nonwhite ethinicities, eye color variation exists without any White heritage-Wikipedia





EDIT:Kourosh Sadeghi ';Official 鈩?,Iranians/Persians are IndoEuropean Aryan Whites.
This is true. The only non white people that have them are mixed with white or are wearing colored contacts and have dyed their hair.





We are just lucky I guess :)








EDIT: To Kouroh or whoever, Irianians are mixed with white, idiot lol. Well no, they are caucasian. If you didn't have caucasian genes you woulden't of got green eyes.





My eyes are green and i'm Irish.
hehehe LOL the first answer .
