Vedclass · Answer

(C) The correct answer is $(c)$.The phenomenon where both alleles of a gene pair express themselves equally in a heterozygote is known as codominance.In the case of $ABO$ blood grouping in humans,the alleles $I^A$ and $I^B$ are codominant.When both $I^A$ and $I^B$ are present together in an individual (genotype $I^A I^B$),both alleles express their respective antigens ($A$ and $B$ proteins) on the surface of red blood cells independently.This results in the $AB$ blood group phenotype,which is distinct from both the $A$ blood group and the $B$ blood group,demonstrating that neither allele is dominant or recessive over the other.
