Which of the following factors would not contribute to allopatric speciation?
a.A population becomes geographically isolated from the parent population.
b.Genetic drift occurs in two populations that are separated by a geographic barrier.
c.An 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 (breeding) between the two populations is extensive.
