Please help!!!! very confused pt 2
Schach [20]

Answer:

If the genotype of the parents are <em>Iᵃi </em>and <em>I</em>ᵇ<em>i, </em>then four type of offspring will be produced.The genotype of the offspring are, <em>IᵃIᵇ, Iᵃi,Iᵇi, </em>and <em>ii.</em>

Explanation:

<em>IᵃIᵇ = </em>As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

<em>Iᵃi= </em>In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

<em>Iᵇi= </em>In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

<em>ii= </em>This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.
