Question

In cats, the eye color green (G) is dominant to the brown eye color (g). What is the genotypic ratio of the offspring of a heterozygous green eyed female and a brown eyed male?

Answer 1

Let's draw a punnet square to depict the genotypic ratio of the offspring of a heterozygous green-eyed female and a brown-eyed male:

g g

G Gg Gg

g gg gg

The results from the punnet square show that the genotypic ratio will be 2:2. There will be 50% chances that the offsprings from these parents will be heterozygous green ad the female parent and there is also a 50% chance that the offspring from these parents will have brown eyes like the male parent.
