d. an O child from a mating of a B parent and an A parent
e. an A child from a mating of an AB parent and a B parent

Explanation / Answer

a) Possible (Parent Genotype should be AO so as to have Child genotype to be O/A Blood Group)

b) Possible (Genotype of Parents should be AO so as to get Genotype of Child be O/A)

c)Not Possible (Parent Genotype AO or AA and Child Genotype Should be AO or OO or AA)

d) Possible ( Parent Genotype should be AO and BO then child can have O/B/A/AB blood group

e) Possible ( Parent Genotype should be AB and BO then Child blood group to be AB/A/B)
