Black One
Why are couples with baby twins is a cause of mixed racing Blacks and whites see the other one?

They always get it Every few years, it shows what happens to cause it. You own a black man in the mix and there is a twin Parent and one white parent or both parents have a visible white Looks like another black man, that is the cause.

Of a different color Evolution is thought to occur as follows: : Modern primates, the head of a large ape-like human ancestors, and their The skin was light in the head. When Hominids evolved relative hairlessness that (among them Was to promote perspiration, the most likely function), They, and they lived in sun-rich Africa, after folate Needed to prevent low-level evolution of black skin. ( Skin cancer generally result only after reproductive age, many evolutionary Does not exert selective pressure due to kill cancer link Is probably one of the secondary importance.) North of the human Less concentrated in the sun, low vitamin D3 levels of migration The problem was with the light skin color re-emerged. (Sexual selection and A good diet can play a role in the development Living a special case: even though they work extremely dark Inuit and Yupik The skin - and their relatively poor environment, they have Keep the skin) as well tone diversity. This very high concentration of Can be explained due to the fact that (their traditional fish-based Diets that provide large range from almost black, the number of Vitamin D of human skin, the dark color almost (colorless, brown show Melanin), red skin due to blood) of others White. The amount and type of skin color is determined by melanin, In the skin pigment. Rather than environmental causes significant variations in skin color Is genetic. In the tropics (and therefore greater exposure to sunlight) in Since the general pattern of ancestry and subtropical regions of the ancestors Than people with darker skin. How much light the skin of a group Be managed by the equator, because the survival of this until now Hard and fast rules, but is socially adapted. The same Melanin. Subtropical latitudes may have dark skin in all groups Life comes in two types: pheomelanin (red) and eumelanin (very dark Brown). 2 Enter the amount of defective genes under the control of the operating 4-6 Is determined by. One copy of each gene from each parent Will inherit. Each allele of the gene in several good Provides the results of a variety of different skin tones. Then the blood is not the type of Totally dominant inheritance like degeneration. Fraternal twins 25% of their genes in common with 50% (depending on the situation and share Whether you can not have something in common They were both in the single- Separate eggs, oocytes, or to split the time of the modification), identical in their 100% of the genes that are shared by twins. So, with the fraternal twins, It is perfectly possible for a fair skin than other displays. And 100% are people of African ancestry and those who have 'Passed as white.
