The coat color gene of a population of squirrels is defined by a dominant allele G, which encodes a gray coat, and a recessive allele g, which encodes a black coat. In a population, genetic typing reveals the genotypic distribution to be 50 GG, 30 Gg, and 20 gg. What is the allelic frequency of the g allele?
A - .40
B - .30
C - .35
D - .25
Answer: C - .35
Allelic frequency is calculated with the equation:
q = b/B+b and p = B/B+b
p is often used to represent dominant alleles and q is used for recessive alleles
