You are studying a population of 100 lizards that has two alleles at a locus for skin color, blue (B) and green (G). There are 30 individuals with the BB genotype, 30 individuals with the BG genotype, and 40 individuals with the GG genotype.

(a) What are the allele frequencies of B and G in the starting population? Show your calculations.

(b) Is this population in Hardy-Weinberg equilibrium? Show your calculations.

Solutions

Expert Solution

Ans:

(a) The calculated allelic frequencies of B and G are 0.45 and 0.55 respectively. The calculation is given below-

(b) The population is not in Hardy-Weinberg equilibrium because the calculated chi-square value 15.61 is higher than the table value 3.8 at 1 DF (5% probability level). The calculation is given below-
