How is skin color determined among humans?

Answer 1

Like most features, hair colour is caused by a combination of your genes and your environment.

The genes involved in determining hair colour have not yet been fully worked out. We know that natural hair colour depends on the amounts of two substances in the hair: eumelanin and pheomelanin.

Blondes have a small amount of eumelanin; brown haired people have a higher level and black haired people have the most.

Pheomelanin determines how red your hair is: the more pheomelanin, the redder it is.

The amounts of these pigments depend on the genes you inherit from your parents, but they can also be changed by your environment eg if you spend a long time in the sun, your hair will bleach.

Answer 2

There are multiple genes that determine a persons skin tone. A white child can be born (rarely) to black parents and vice versa. If two white parents have a black child there must be an African ancestor. If two black people have a white child, the baby will be considered albino.

Answer 3

Genetics! Lets say the alleles for eye color are C and c. Parent A is homozygous dominant for green eyes, so they would have the genotype "CC". Parent B may be Homozygous recessive, meaning they have the genotype "cc". In this case, if you were to draw a Punnett square, you would find that the child would be Heterozygous, and they would end up with green eyes.*Heterozygous-the alleles are different (hetero) one dominant, one recessive. The genotype is "Cc". The child's phenotype ends up with the dominant gene. In order to determine breeding capabilities, create a Punnett square.

Answer 4

it depends where you were born like if you born in Africa your skin would be black because of the sun and heat a bit like a tan.

and that's gods way

Answer 5

by your parents
