B. Let's assume that a small proportion of the homozygote ss individuals do survive and reproduce, but they produce (on average, only 10% as many offspring as homozygote SS and heterozygote Ss individuals. Let's also assume that these SS and Ss types don't differ in their reproductive success. Finally, let's specify that the starting frequencies of the S and s alleles (p and q) are 0.8 and 0.2, respectively. Given these values, please solve for p' and q', the frequencies of S and s after one generation of selection. Has anything changed? Does that make sense? Please show your work!
