Question

A skin and respiratory fungus killed most of the tree frogs in a hypothetical forest in the state of Washington. The population dropped from 1,200 to 320. Scientists caught 25 frogs and, in an effort to help preserve the species, started a new population in a similar forest in the eastern portion of the state of Oregon. Which of the following factors would probably have the least impact on this new population? A. The founder effect, since there would be a large population with immigration. B. Random mating, since this affects populations regardless of size. C. Genetic drift, since the small population will have variability in allele frequency. D. The bottleneck effect, since the small population will go through a decrease in allelic variability.
