For the following population determine if the population is in Hardy-Weinberg Equilibrium. Round to two decimal places. AA: 15 Aa: 22 aa: 63 What are the genotype frequencies? What are the allele frequencies? What are expected/predicted genotype frequencies?
Ans:
The calculated genotypic frequencies are -
AA = 0.07
Aa = 0.38
aa = 0.55
The allelic frequencies of A and a are 0.26 and 0.74 respectively.
The expected/ predicted genotypes are-
AA = 7
Aa = 38
aa = 55
The calculated chi-square value 17.04 is higher than the table value 3.84 at 1 DF (5% probability level). This significant deviation between observed and expected value signifies that the population is not in Hardy-Weinberg equilibrium.
All the calculation is given below-
