Scientists were monitoring the fluctuations in the frog population at a rural pond. Because the pond was densely populated with grasses, shrubs, and small trees, they hypothesized that the green frogs would eventually be the predominant color within the population. Their observations revealed that 16% of the initial population was brown. That is 16% showed the recessive trait for color. What is q, the frequency of the homozygous recessive allele, for this population?
A) 0.4
B) 0.2
C) 0.0
D) 1.2
