AP Biology Heredity

A father with type B blood and mother with type A blood have a child. Their child has discovered that her blood group is type O, during biology experiment at her school. Does she have any concerns about her parentage?

• Yes, because she should have type AB blood if they are her true biological parents

• No, because type O is possible if her parents both had genotype AB

• No, because both of her parents could be heterozygous

• Yes, because both of her parents might be hetrozygous

• No, because blood types A and B are codominant
