Consider a racoon population that exhibits variation at the G locus, which has two possible alleles: G1 and G2. The population starts out at Hardy Weinberg Equilibrium and the frequency of the G1 allele in the original population is 0.3. The relative fitness of each genotype during this generation is listed below. Use information to answer the following questions.

w11 = 0.8

w12 = 1.0

w22 = 0.5

Calculate the average fitness for the population.

Calculate the genotype frequencies in the next generation.

Calculate the frequency of the G1 allele in the next generation.

Calculate the frequency of the G2 allele in the next generation.

Calculate the change in the frequency of the G1 allele in the next generation.

the frequency of G1allele is given, p= 0.3,

frequency of G2 allele will be, q= (1-0.3) = 0.7

now average fitness of the population can be calculated as

w= p2w11+2pqw12+q2w22 = (0.32x0.8)+(2x0.3x0.7x1)+(0.72x0.5)=0.737

now genotypic frequency in next generation will be

G1G1 genotype = p2 x (W11/avg W) = 0.32x (0.8/0.737)= 0.097

G1G2 genotype = 2pq x (W11/avg W) ) = 2x 0.3x 0.7 x (1/0.737) = 0.57

G2G2 genotype = q2 x (W11/avg W) = 0.72x (0.5/0.737) =0.33

frequency of G1 allele in next genetation = 0.097+( 0.57/2) = 0.382

Frequency of G2 allee in next generation=0.33+( 0.57/2) = 0.615

change in frequency of the G1 allele in next genration = ( 0.382-0.3)/0.3 *100= 27.3%
