Question
Inheritance pattern of ABO blood groups in humans shows dominance, codominance and multiple allelism. Explain each concept with the help of blood group genotypes.
✓
Answer
In the first case of inheritance of blood group there are three alleles IA, IB and i out of which we inherit any two of them - multiple allelism.
In case of AB group the alleles are IA and IB and both are expressed – codominance.
In case of IA i and IB i which are heterozygous the dominant gene expresses – law of dominance.
