Which of the following factors would not contribute to allopatric speciation?
A) A population becomes geographically isolated from the parent population.
B) The separated population is small, and genetic drift occurs.
C) The isolated population is exposed to different selection pressures than the ancestral population.
D) Different mutations begin to distinguish the gene pools of the separated populations.
E) Gene flow between the two populations is extensive.

Gene flow between populations keeps their gene pools similar and prevents them from diverging enough to become different species. Therefore, extensive gene flow between two populations would not contribute to allopatric speciation.
