Begin by noting the total population size and the genotype counts provided: 100 squirrels total, with 16 rr, 36 RR, and 48 Rr. Next, calculate how many total alleles are present in the population. Each individual has two alleles for the gene, so there are 100 × 2 = 200 alleles in total. Now tally the number of r allel......Login to view full explanation
