1. The problem statement, all variables and given/known data Out of a total of 43 people, 15 contain the genotype TT, 16 with Tt, and 12 with tt. Need to determine the allelic frequency of the recessive allele t. 2. Relevant equations 1=p2+2pq+q2 1=p+q 3. The attempt at a solution By counting up the individual alleles and divided by the total alleles in this question, I get a different answer than by using the Hardy-Weinberg equation. Total t alleles add up to (16 in the heterozygotes and 24 total in the homozygous recessive genotypes) 40. Dividing 40 by 86 gives a value of around 0.47. Using the Hardy-Weinberg equation, where the 12 is divided by 43 to get the genotype frequency, and then square-rooted, a value of 0.53 is obtained for the frequency: a significantly different number than the 0.47 previously counted up. What is the correct solution?
