Question
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.Explanation / Answer
B2 allele is Recessive beneficial.
As in B1B2 genotype, it is clear that B1 allele is dominant.
