Question

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of frogs, 50 are homozygous for the dominant trait, 34 are heterozygous dominant, and 16 show the recessive trait. Which expression is the correct way to calculate the frequency of the dominant allele?

Answer 2

Correct Answer: D - 134/200
Explanation: p = the frequency of the dominant allele in a population.
q = the frequency of the recessive allele in a population.
2p q 2pq 2pq = the frequency of the heterozygous dominant genotype.
p 2 p^2 p2 = the frequency of homozygous dominant genotype
