Use the following scenario to answer Question 7-9: The hypothetical Western Chickadee composes three major populations Pacific Great Basin and Rockies in the chickadees the bill color gene has two alleles (B_1 & B_2) Relevant information about genotypes and the populations follows Populations Pacific N =350,000 f(B_1) =0 97 Great Basin N =450,000. f(B_1) = 0 96 Rockies N = 750,000 f(B_1) = 0 98 B_1B_1 bill color = black, relative fitness = 1.0 B_1B_2 bill color = black, relative fitness = 1.0 B_2B_2 bill color = black, relative fitness = 1.6 Which of the following options describe the B_2 allele? Dominant beneficial Dominant Deleterious Recessive beneficial Recessive deleterious There is not enough information provided to determine this.

Solution

B2 allele is Recessive beneficial.

As in B1B2 genotype, it is clear that B1 allele is dominant.
