Question

In humans, almond shaped eyes are dominant to round shaped eyes and long eyelashes are dominant to short. A man who has round eyes and homozygous long eyelashes marries a woman who is heterozygous for both trait. Determine the phenotypic ratio. If they have 8 children, how many will have almond shaped eyes with long eyelashes?

Answer 1

Phenotypic ratio - 2 almond eyes and long lashes: 2 round eyes and long lashes

0.5 (from the ratio) x 8 (children) = 4

4 children will have almond eyes with long lashes

Hope this helps!
