Consider a gene with three alleles. On the graph below, there are two lines indicating the frequency of two of the three alleles over time. Fill in the graph with the line that shows the frequency of the third allele (r). Hint: what do allele frequencies for a gene add up to? Allele Frequency 0.6 0.5 0.4 0.3 0.2 0.1 0 P 0 1 2 3 4 5 6 7 8 9 10 Generation
