Answer:The mother has a heterozygous blood type A, meaning her genotype is AO. The father has a homozygous blood type B, meaning his genotype is BB. Here's the Punnett square showing the possible blood types of their offspring: B B A AB AB O BO BO Possible Blood Types of Offspring: - AB: 50% chance (codominant, both A and B alleles are expressed)- B: 50% chance (the B allele is dominant over the O allele) Key: - A: Blood type A allele- B: Blood type B allele- O: Blood type O allele Therefore, the offspring have a 50% chance of inheriting blood type AB and a 50% chance of inheriting blood type B. There is no chance of the offspring having blood type A or O in this scenario.
