Question

Is skin colour an example of incomplete dominance in humans?

Answer 1

Skin colour:

1. Incomplete dominance refers to a specific gene interaction in which a dominant allele can not fully inhibit the expression of the recessive allele.
2. Multiple genes control skin colour.
3. It shows polygenic inheritance.
4. Skin colour defines incomplete dominance.
5. Most of the skin colour is the result of two blended alleles and thus produces different skin tone.
6. Each of the alleles contributes to expressing the final phenotype.
