Question

16. In a population of dragonflies, 2 alleles of the G gene exist and control wing length; the alleles show incomplete dominance where GG results in long wings, Gg results in medium wings, and gg results in short wings. Given the number of individuals and absolute fitness for these genotypes, answer the following. P W Genotype GG Gg gg N 98 144 55 W 1.2 2.5 1.9 a. Fill in the values for genotype frequency (P) and relative fitness (w) for each genotype. b. What are the current allele frequencies? c. What will be the genotype frequencies in the next generation?

Answer 1

Please look in the image for solution:

Genotypic frequency (P) arc following G9 98 0-3299 M0.33 297 1 144 297 = 0.4848 m0.48 ११ 55 297 = 0.185 n 0.19 Relative fitness (w) - Fitness / max. fitness GG = 1.2 = 0.48 2.5 G9 = 2.5 - 2.5 gq 1.9. 2-5 - 0.76
