Question

Is human eye color incomplete dominance?

Answer 1

Incomplete dominance:

1. A cross in which each genetically distinct parental contribution results in progeny with an intermediate phenotype causes incomplete dominance.

Is human eye color incomplete dominance:

1. An intermediate form of inheritance different from parents is known as incomplete dominance occurs when one allele for a given feature does not fully express over the dominant allele.
2. Polygenic inheritance of traits like skin color and eye color exhibits this form of dominance.
3. Eye color:
   1. The color of the eye is determined by polygenes and incomplete dominance.
   2. At least 9 colors of eye color are recognized in humans.
   3. There are two major eye color genes and 14 more genes which determine the expression of the phenotype.
   4. A different number of alleles contribute to each color.
   5. These are found to be X-linked.
