Question

A blue eyed boy was born in a family where both parents are brown-eyed.What kind of variability manifested itself in this case?Explain all the possible mechanism of such variability.

Answer 1

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.
