Question

A woman with blood group o married a man with ab group. show the possible blood groups of the progeny.list the alleles involved in this inheritance

Answer 1

Solution:

The progeny of the resultant blood group can either be A or B.

The dominating gene in this case will be IA and IB.

As O is a homologous group, therefore IAIB would dominate IO in the particular phenotype and genotype of the progeny.

In such a case, the blood group would be A or B.

Answer 2

The progeny would have either A or B as their blood groups.

b)The genes IA and IB are dominant over the gene IO but are codominant with each other. Hence , IAIA/IAIO would result in the ‘A’ blood group, IBIB/IBIO in ‘B’ blood group, IAIB in ‘AB’ blood group and ‘O’ only in IOIO condition.
