Question

What if the dominant trait in genes for blood group in female is A and male is B What will be blood group of offspring

Answer 1

Blood group of offspring can be A, B ,AB, O.

Answer 2

Dominant alleles will mask recessive alleles. In the case of blood type, A and B are both dominant over O. Therefore if you inherit one A or B allele and an O allele, your blood type will be the dominant type (A or B). This also means that the only way for someone to have type O blood, is if they have two O genes.
