biologically what separates different races?

Question

basicly is the dna structure of a black person for example different from a white person, what is the chemical formular or whaterver that makes people the color they are?, what seperates different skin colors in human beings?

Answer 1

There is more genetic variation between some tribes in Africa than there is between those of African descent and those of European.

All humans have the same DNA structure. Thus, no, the DNA Structure of a 'black' person is not different than that of 'white' person, they are essentially the same with minute variations. These are so minute in fact, that you and someone with the same skin color could have less biologically in common than you could have with someone of a different skin color.

Skin color is determined by a relatively small set of genes.

Answer 2

There is actually no genetic basis to "race". In fact there is greater variance in DNA among members of a race, than there is between separate races. Skin color is a result of both environmental and genetic factors. The genetic factor involves a combination of many genes that encode a protein called melanin. So populations with darker skin have ancestors who evolved to favor genes which led to expression of darker skin, which probably served as protection to hairless skin.

Answer 3

there is extra genetic version interior a agency of chimps living interior a similar woodland in Africa than interior the full human race. we are all Homo sapiens sapiens and are surely really homogenous in evaluation to diverse species. that is once you consider that for the length of the migration of the earliest adult males and females out of Africa, the inhabitants of adult males and females thoughts a bottle-neck very last effect. Our numbers were each and each and every of how right down to variety of 20, 000 or so. This severly decreased inhabitants resulted interior the decreased genetic version we've were given at modern-day. human beings are puzzling-less than pressure out to appreciate differences among our own species, although regrettably this has presented about our over-emphasizing those differences. in truth, they are very superficial differences correct to differences to one in all a form environments. in case you really look at adult males and females objectively, although, you'll comprehend that we are ridiculously equivalent in evaluation to diverse species. Like portray a similar position of living an additional coloration and chanding the roof and door. The structure, continues to be a similar.

Answer 4

Racial differences are based on appearance, not genetics. We are all descended from Africans, if you look far enough back.
