What is the relative fitness of the recessive homozygote? 20. Given a population with the following genotypic frequencies among offspring at birth f(BB) = 0.64, f(Bb) = 0.32, f(bb) = 0.04, and the following fitness values WBB = 0.5, WBb = 1.0 and Wbb = 0.6, a. what will be the frequency of each genotype after selection? B. What are the allele frequencies after selection? C. What genotypic frequencies are expected at birth in the next generation? D. How much change has there been in the frequency of the B allele in one generation? 21. Given a population with the following genotypic frequencies among offspring at birth f(BB) = 0.20, f(Bb) = 0.49, f(bb) = 0.31, and the following fitness values WBB = 0.5, WBb = 1.0 and Wbb = 0.6, a. What will be the frequency of each genotype after selection? B. What are the allele frequencies after selection? C. What genotypic frequencies are expected at birth in the next generation? D. How much change has there been in the frequency of the B allel
