Calculating Expected Genotypic Frequency
In a population of squirrels, coat color is determined by a dominant allele G, which encodes a gray coat, and a recessive allele g, which encodes a black coat. Genetic typing reveals a genotypic distribution of 50 GG, 30 Gg, and 20 gg. If this population were in Hardy-Weinberg equilibrium, what would be the expected genotypic frequency of GG squirrels?
A

B
0.52
C
