3 Blood types are described based on the proteins they have or don't have. There are two genes that control
these proteins. The first has multiple alleles: A, B and O. The second gene codes for the Rh factor that is either
present (+) or absent (-). A woman heterozygous for both genes has the blood type A+. If the woman and a man
with blood time 0-, have a baby, what are the possible genotypes and phenotypes of the baby. Use a Punnett
square to show your work.
