# of B alleles f(B) allele = total # of alleles (= 20) Example: 2000 2005 Phenotype Frequencies f(black) f\white) Genotype Frequencies f(BB) f(Bb) f(b) Allele Frequencies f(B) f(b) 2. Data Analysis Using the information from the table in question 1, answer the following questions. Did the phenotype frequencies change over time? In what way? a. Answer: b. Did the genotype frequencies change over time? In what way? Answer: с. Did the allele frequencies change over time? In what way? Answer: d. Think of a possible reason why this change might have occurred. Answer:
