Vedclass · Answer

(D) Codominance is a phenomenon where both alleles of a gene pair are expressed equally in the heterozygote. Unlike incomplete dominance,where the phenotype is a blend,in codominance,both parental traits appear distinctly. $A$ classic example is the $ABO$ blood grouping system in humans,where individuals with genotype $I^A I^B$ express both $A$ and $B$ antigens on their red blood cells.
