Question
2.You have discovered a population of Drosophila in which some flies have a single eye in the middle of their head and you have designates this phenotype cyclops. You determine the cyclops phenotype is recessive (cc). Cyclops flies have a low fecundity because they have a difficult time attracting a mate and have a relative fitness of 0.1. The wild type (CC) and the heterozygote (Cc) have relative fitness of 1.000 and 0.658, respectively y. The genotype frequency for the homozygous wildtype fly is 0.699 and the heterozygous is 0.274. What is the genotype frequency of the heterozygote after one generation of mating?
Explanation / Answer
geneotype frequencof heteryzygote= differentce of relative fitness/difference of geneotype freq
=1-0.658/0.699-0.274=>0.342/0.425=>0.80
