What color eyes are more dominant than blue?

brown eyes
The bey2 gene has one allele for brown eyes and one for blue eyes. The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.

Are blue eyes better than brown?

A brown iris absorbs more light than a lighter blue or green iris, which may directly lead to quicker reaction times. A sports correlative study at the University of Louisville reports that brown-eyed people perform better at reactive tasks such as catching or hitting. But, if you have blue eyes, don’t worry.

Are brown eyes always dominant?

However, brown eyes aren’t a completely dominant trait, so different combinations of the eye genes will result in slight variations of eye color. Genetically, this is fairly normal — the gene that does something is dominant, while the gene that doesn’t do it is recessive.

What eye color is recessive?

What Determines Eye Color? Homozygous And Heterozygous Human beings have two copies of every gene. Dominant Eye Color Brown and green are dominant eye colors. Recessive Eye Color Blue is a recessive eye color. Genotype The genotype is the gene combination for a given trait, which, in this case, is the eye color.

Why are brown eyes dominant?

In humans, brown eyes result from a relatively high concentration of melanin in the stroma of the iris, which causes light of both shorter and longer wavelengths to be absorbed. Dark brown eyes are dominant in humans and in many parts of the world, it is nearly the only iris color present.

Are green eyes dominant or recessive?

Yes, green eyes are a recessive trait. The heredity of eye colour involves two genes so it isn’t completely predictable but green eyes are recessive since they involve some of the same pigmentation alleles that produce blue eyes which are recessive.
