Vedclass · Answer

(A) Codominance is a phenomenon where both alleles of a gene pair express themselves equally in the heterozygote.In the case of human $ABO$ blood grouping,the gene $I$ has three alleles: $I^{A}$,$I^{B}$,and $i$.When $I^{A}$ and $I^{B}$ are present together in an individual,both alleles express their respective sugars on the surface of red blood cells.Therefore,the genotype $I^{A}I^{B}$ represents codominance,resulting in blood type $AB$.
