20) Consider a trait specified by a single genetic locus with two alleles, B and b. In a particular environment, heterozygous individuals have the highest fitness. BB individuals have a fitness value that is 85% of heterozygous individuals. Calculate the selection coefficient (s) for BB individuals in this environment. (Show your calculation)

Expert Solution
Step 1

The difference between fitness or the change in genotype frequencies is termed as the selection coefficient. Fitness means the reproductive rate or survival rate of organisms relative to the maximum reproductive rate or survival rate in a population.
