If a population exhibits a relative fitness of the wild-type (AA)genotype of 0.8,and that of the heterozygote (Aa)of 1.0,then the relative advantage in fitness of the heterozygotes would be

Question

Quizplus · Accepted Answer

The relative advantage in fitness of the heterozygotes is calculated as the difference between the relative fitness of the heterozygotes and the relative fitness of the wild-type homozygotes. In this case, the relative fitness of the heterozygotes is 1.0 and the relative fitness of the wild-type homozygotes is 0.8. Therefore, the relative advantage in fitness of the heterozygotes is 1.0 - 0.8 = 0.2.
