Is skin color a single gene trait?

Is skin color a single gene trait?

A polygenic trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic.

Which genes have the same alleles?

An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous.

Why can humans only have 2 alleles?

Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other.

What is Gene short for?

Originally a short form of Eugene (well-born), Gene is commonly bestowed as an independent given name.

What genes are responsible for eye color?

Finally, two major genes are responsible for eye color: HERC2 and OCA2. During the first studies to classify genes for eye color, OCA2 was believed to be the dominating factor for eye color determination.

Can 2 blue eyes make a brown?

Someone with broken OCA2 genes will have blue eyes no matter what the HERC2 genes are. Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child.

How can I change my eye Colour?
