A population of 1000 individuals is determined to have these genotypes at the A locus: 400 AA, 400 Aa, and 200 aa. What are the frequencies of the A and a alleles (values of p and q), in this population?
total number of individuals= 1000
number of aa individuals= 200
genotypic frequency of aa= number of aa individuals/total number
= 200/1000
= 0.2
frequency of allele a= square root of genotypic frequency of aa
= square root of 0.2
= 0.447
frequency of allele a+ frequency of allele A= 1
frequency of allele A= 1- frequency of allele a
= 1- 0.447
= 0.553
