Question

In squirrels, the gray allele (G) is dominant to the brown allele (g) at the coat color locus. A population of 254 squirrels in Pullen Park was scored for the coat color locus. The frequency of the gray allele was found to be 0.83. Due to construction at NC State, 16 NC State squirrels migrated to Pullen Park. The frequency of the gray allele in the NC State squirrels was 0.26. The squirrels mated randomly to form a progeny generation at Pullen Park. Assuming that no further migration occurred and that all other conditions for Hardy-Weinberg equilibrium were met, what is the frequency of the gray allele in the progeny generation at Pullen Park? Round your answer properly to 4 decimal digits.

I need help understanding how to work this problem, not just the answer...please show steps taken. Thanks!

Explanation / Answer

Frequency of gray allele = 0.83 for 254 squirrels

Frequency of gray allele = 0.26 for 16 NC state squirrels which migrated to Pullen Park

Total number of squirrels in Pullen park = 254 + 16 = 270

frequency of the gray allele in the progeny generation at Pullen Park = (0.83 * 254 + 16 * 0.26) / 270

frequency of the gray allele in the progeny generation at Pullen Park = 0.7962
