Question

If a blue eyed offsprings is formed from black eyed parents, what type of chararacyer the blue eye is dominant or recessive? Write with reason? Also give a chart?

Answer 1

In humans, blue eye color is a recessive eye color.

Let's designate A - black eyes, and a - blue. Then the offspring with blue eyes should have the aa genotype (recessive homozygote). For parents with black eyes to have such offspring, they must be with the Aa genotype (heterozygote). This is explained by Mendel's second law.
