Populations are said to be allopatric when ................
Populations are said to be allopatric when ................
Updated On: Apr 16, 2024
- They are physically isolated by natural barriers
- They are sharing the same area but cannot interbreed
- They live together and breed freely to produce viable offspring
- They are isolated but often come together for breeding
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In allopatric speciation, a part of the population becomes geographically isolated from the main population. The population becomes entirely separated and finally constitutes a new species. Thus, geographic isolation brings about allopatric speciation. An important example of allopatric speciation is formation of Darwin�s finches that formed separate species in the Galapagos islands.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
