Question

in human almond shaped eyes (A) dominate to round shaped (a) recessive. Cross a woman who is homozygous dominant with a man who is a homozygous recessive. Determine the phenotype and genoype ratio their offspring. Use a Punnett Square to show answer ​

Answer 1

Will assume the alleles are not sex-linked.

The woman's homozygous dominant genes are AA, the man's homozygoous recessive are aa, so from the Punnett Square below:

       A    A

a     Aa  Aa

a     Aa   Aa

We conclude that the offsprings are 100% heterozygous Aa as phenotype, and because A is dominant, so they all have almond shaped eyes.
