Question

A woman with homozygous type A blood (AA) marries a man that has heterozygous type B blood (BO). What are the couple's chances of having a child with type AN blood?

Answer 1

Well there are four blood types, A, B, AB, and O. So the chances of the child having a AN blood type are negative. Then again if the wife has AA blood type and the dad has Bo blood type the AN would stand for -A. So it would be a 25% chance that the child would have blood type AN
