Vedclass · Answer

(A) The $MN$ blood group system is determined by a single gene locus with two alleles,$L^M$ and $L^N$.These two alleles exhibit co-dominance,meaning that in the heterozygote $(L^M L^N)$,both alleles are expressed equally.As a result,individuals with the genotype $L^M L^M$ have $M$ antigens,those with $L^N L^N$ have $N$ antigens,and those with $L^M L^N$ have both $M$ and $N$ antigens on their red blood cells.Therefore,the $MN$ factors are due to two co-dominant genes $M$ and $N$.
