Question

Human blood type is determined by multiple alleles (A, B, and O). Which ratio would result from a cross between a man with homozygous Type A blood and a woman with Type O blood?

Answer 1

Hallo~~

Your question is related to genetics.

Have you ever done a Punnett Square? This question forces you to make one. If your cross a homozygous type A (AA) and homozygous type O (OO) you should get 100% AO. Understanding genetics, an AO gene means a type A blood. Therefore, it's 100% type A blood (AO).
