A person's blood type is determined by the combination of three alleles IA, IB, and i. The possible blood types of the child born from A0 and BB parents are AB and B.

What is the ABO group?

The I gene determines the blood type of a person. This is a triallelic gene that expresses complete dominance and codominance.

Alleles

  • IA allele is dominant over the i allele. The person presents A type of antigens.
  • IB allele is dominant over i. The person presents B type of antigens.
  • IA and IB alleles express codominance. In this case, the person presents both types of antigens, A and B.
  • i is the recessive allele. The person does not present any antigen.

Genotypes and Phenotypes

  • H0m0zyg0us dominant or heter0zyg0us Individuals IAIA or IAi will express the A blood type.
  • H0m0zyg0us dominant or heter0zyg0us Individuals IBIB or IBi will express the B blood type
  • Individuals with h0m0zyg0us recessive genotype ii will express the 0 blood type.
  • Individuals carrying IA and IB alleles will express the AB blood type.

Now, in the exposed example

Cross: A0 x BB

Parentals) IAi     x     IBIB

Gametes) IA    i       IB     IB

Punnett square)     IA         i

                        IB   IAIB    IBi

                        IB   IAIB    IBi

F1)  1/2 = 50% of the progeny is expected to be IAIB and have AB blood type

      1/2 = 50% of the progeny is expected to be IBi and have B blood type

The possible blood types are AB and B.
