Antigens on red blood cells are hereditary traits that allow blood to be typed in different ways. one system is based on a gene with two alleles, m and n. if the frequency of the m allele in a population is 0.4, then according to the hardy-weinberg rule, the expected frequency of the heterozygous mn genotype is

Antigens on red blood cells are hereditary traits that allow blood to be typed in different ways. One system is based on a gene with two alleles, M and N. If the frequency of the M allele in a population is 0.4, then according to the Hardy-Weinberg rule, the expected frequency of the heterozygous MN genotype is 0.48.
