Question

List the 6 possible genotypes of the four blood types. Identify the parentalgenotypes that could produce children with blood type AO.

Answer 1

The different possible genotypes are AA, AO, BB, BO, AB, and OO. These are derived according to the A, B and O blood group model.

The table is given below:

Blood Type Genotype

Blood Type A Genotypes AA or AO

Blood Type B Genotypes BB or BO

Blood Type AB Genotype AB

Blood Type O Genotype OO

The alleles A and B exhibit a greater dominance than O. This is the reason why the Parent of Blood type A will form the Genotype AO.
