Which of the following describes allopatric speciation? Multiple Choice A single population suddenly divides into two reproductively isolated groups without being geographically isolated. A geographic separation occurs between subpopulations leading to reproductive isolation. Gene flow between subpopulations minimizes differences in their gene pools. Subpopulations that are geographically isolated but still able to interbreed. Wide phenotypic differences that appear between subpopulations due to variation in their environments.

This does not describe allopatric speciation, as it involves reproductive isolation without geographic separation. Option B: A geographic separation occurs between subpopulations leading to reproductive isolation. This option describes allopatric speciation, as Show more…

Joanna Q.
Which of the following factors would be the most likely to contribute to allopatric speciation? (A) The separated population is large, and genetic drift occurs. (B) Selection pressures in the isolated population are similar to those in the ancestral population. (C) Gene flow between the two populations is extensive. (D) Different mutations begin to distinguish the gene pools of the separated populations.
