Answer #1

IN first case that means Shirley's case her partner is Curties because his blood group is O,because Eachh biological parent donates one of their two ABO alleles to their child.

In second case childs father is Darryl because a mother who is blood type A can only pass A allele to her son or daughter, A father blood group AB could pass either an A or B allele to his son or daughter.

In third case the possible birth type of their chikdren are blood group with B,O. because father who is blood type O can only pass O allele to his child the same way the mother can pass B so the child will have the blood group O or B
