Question

The development of a housing complex on woodland has separated a single population of chorus frog into two populations. Some frogs do manage to cross the development, moving from one population to the other. Considering the likelihood of speciation, the result of this movement of individual frogs is that speciation:
A) becomes less likely because the two genes pools remain similar
B) remains unaffected because habitat destruction reduces species diversity
C) becomes more likely to occur because migration changes allele frequencies
D) remains unaffected because there is little competition between the two populations
Eliminate

Answer 1

a. becomes less likely because the two genes pools remain similar 

Answer 2

Answer: A) becomes less likely because the two genes pools remain similar

Explanation:

Speciation is a process by which a new species develops from the existing species when the populations of the same species get separated by geographical, temporal and behavioral barriers.

According to the given situation, as it is mention that the two separated populations of the chorus frog by the barrier woodland is cross by the members of the population. This condition will not bring variations in the gene pool of the two populations. This makes the speciation less likely to occur.
