1. For a particular species, assume that there are three alleles at a locus for color. These alleles are B1 , B2, and B3 . Also, there is a hierarchy of dominance such that B1 > B2 > B3 . The relationship between genotypes and phenotypes is that B1B1 , B1B2, and B1B3 are black, B2B2 and B2B3 are brown and B3B3 is yellow. (2 pts) A. If the population is in equilibrium and the phenotypic frequencies are: Phenotype Frequency Black .84 Brown .07 Yellow .09 What are the frequencies of the three alleles:
