Question

The geographic isolation of a population from other members of the species and the subsequent evolution of reproductive barriers between it and the parent species describes ________ speciation.
1 punctuated
2 sympatric
3 biogeographic
4 allopatric

Answer 1

Answer:

4 allopatric

Explanation:

The formation of a new species can occur in several ways. One such process is the separation of two populations of a species geographically. The presence of any geographical barrier may separate the two populations from each other. These populations accumulate variations over time. After several generations, the members of these two populations can not interbreed successfully and are said to be reproductively isolated. The two populations are now two different species. This is called allopatric speciation.

Answer 2

Answer:

4) Allopatric

Explanation:

Speciation is the formation of the new species from the ancestral species due to much evolutionary force.

The factors which lead to the formation of new species prevent the species to interbreed that is they become reproductively isolated which results in the formation of new species.

One such way of speciation is known as allopatric speciation caused by the separation of the species as a result of the geographical barrier like oceans, mountains etc for a long period of time. This prevents breeding between them as a result of which a new species is formed.

Thus, allopatric speciation is the correct answer.
