Answer: Gene flow between the two populations is extensive
Which of the following factors would not contribute to allopatric speciation?

Allopatric speciation (from Ancient Greek ἄλλος allos meaning “other” and πατρίς patris “fatherland”) also referred to as geographic speciation vicariant speciation or its earlier name the dumbbell model : 86 is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow.

Sat Dec 19 2020 13:30:00 GMT-0500 (Eastern Standard Time) · Speciation ultimately results due to the reproductive isolation between two populations. This can happen in a multitude of ways a common mode of which is known as allopatric speciation .The geographic mode where two species become physically isolated and unable to interbreed allows for selection to act on both populations independently. Over time this gives rise to a new species.

Character displacement is the phenomenon where differences among similar species whose distributions overlap geographically are accentuated in regions where the species co-occur but are minimized or lost where the species’ distributions do not overlap. This pattern results from evolutionary change driven by biological competition among species for a limited resource (e.g. food).

Sympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region. In evolutionary biology and biogeography sympatric and sympatry are terms referring to organisms whose ranges overlap so that they occur together at least in some places. If these organisms are closely related (e.g. sister species) such a …
