Is eye Colour genotype or phenotype?

Is eye color genotype or phenotype?

The visible eye color is your phenotype, but it tells us nothing about your genotype. Multiple different genes affect eye color in humans, and any of them could manifest dominant or recessive traits in your phenotype – that is, the unique shade of brown in your eyes.

Is red eyes a genotype or phenotype?

Heterozygous – genotype XWXw; phenotype: red eyes. Homozygous recessive with two white encoding alleles – genotype XwXw; phenotype white eyes.

Is green eyes a genotype or phenotype?

3. Both green and brown eyes are [ dominant / recessive ] to blue eyes. 4. There are [ one / two / three / four ] possible genotypes for green eyes.

Is eye color an example of epistasis?

Although eye color is usually modeled as a simple, Mendelian trait, further research and observation has indicated that eye color does not follow the classical paths of inheritance. Eye color phenotypes demonstrate both epistasis and incomplete dominance.

Is eye color dominant or recessive?

The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.

What chromosome is eye color on?

Although there are about 16 different genes responsible for eye color, it is mostly attributed to two adjacent genes on chromosome 15, hect domain and RCC1-like domain-containing protein 2 (HERC2) and ocular albinism (that is, oculocutaneous albinism II (OCA2)).
