Problem: M and N are blood groups separate from A, B, and O. It is controlled by two alleles of one gene, LM and LN. People with blood type M are homozygous for , people with type N blood are homozygous for , and people who have blood type MN are heterozygous. Three different human populations have the following MN blood group frequencies shown below.a) What are the allele frequencies for M and N in each population?b) Which populations are in Hardy-Weinberg equilibrium?

🤓 Based on our data, we think this question is relevant for Professor Yeargain's class at UCF.

Following the equation for Hardy-Weinberg equilibrium, p2 + 2pq + q2 = 1. This means that the frequency of the first allele can be computed by getting the root of the frequency of homozygous dominant individuals. Conversely, the frequency of the second allele can be computed by getting the root of the frequency of the homozygous recessive individuals.
