Question

The human blood type is determined by codominant alleles. A woman with type A blood and a man with type B blood could potentially have offspring with which blood types?

Answer 1

Answer:

A woman with type A blood and a man with type B blood could potentially have offspring with either type A or B or AB blood. The mother with blood group A and the father with blood group B can have different phenotypes as given in the table.

Answer 2

CO-DOMINANT ALLELE -

• The inheritance pattern in which the alleles do not mask the effect of each other.
• The Law of dominance is violated as both the alleles are dominant in nature in heterozygous conditions.
• In human blood type, the ABO blood group is an example of co-dominant alleles
• There are three different alleles are$I^A, I^B,$and i forms four different types of blood groups such as A, B, O, AB.
• A woman with blood group A and a man with blood type B can form potentially different types of blood groups as A, B, O, or AB.
• Genotypically the blood types formed are -

      Blood group A -   $I^AI^A, I^Ai$

       Blood group B - $I^BI^B, I^Bi$

       Blood group O - ii

       Blood group AB - $I^AI^B$
