If a mother has type A blood and the father has type AB blood, what are the child's possible genotypes?

Genotype of a child with AB blood group is A parent with A blood group can have two possible : Thus, their children show 50% probability for a blood group AB. But, if mother is heterozybgous . and father is . the total different types of possible combinations by three allele.

. Thus, their children also show 50% probability for a blood group AB. This means that 50% probability for blood group 'AB' children from father with A and mother with blood group B indicates that either of the parent is .

answer; a muscle cell, another neuron and a of the above
