question 131

Multiple Choice

Use the following to answer questions:
Suppose you have a population of flour beetles with 1,000 individuals. Normally the beetles are red; however, this population is polymorphic for a mutant autosomal body color, black, designated by b/b. Red is dominant to black, so B/B and B/b genotypes are red. Assume the population is in Hardy-Weinberg equilibrium, with equal frequencies of the two alleles.
-If the population in the previous question mated randomly and no other evolutionary forces operated, what would be the allele frequencies of their offspring?

• A) 0.875; 0.125
• B) 0.125; 0.875
• C) 0.25; 0.75
• D) 0.75; 0.25
• E) 0.5; 0.5
