OPTIONS:
A) biogeographic isolation affects the random changes that take place within gene pools
B) biogeographic isolation affects the changes in gene pools that result from which organisms are breeding
C) biogeographic isolation determines who will win competition for mates
D) biogeographic isolation determines the time that populations will breed
Answer:
A) biogeographic isolation affects the random changes that take place within gene pools
Explanation:
Organisms can become splitted and isolated from each other by biogeographical factors, thereby preventing the isolated population of species from interbreeding with each other. When this occurs, the isolated population, over time, evolve separately and later become distinct from each other leading to a change in the original gene pool.
Biogeographical factors uch as habitat isolation can cause a change in the original gene of a species population which have now become isolated geographically, and thus, evolve separately.
