Assertion In intraspecific speciation, a single species may give rise to new species
Reason Gene flow within the populations must be interrupted

A

Both Assertion and Reason are true, but Reason is the correct explanation of Assertion

B

Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion

C

Assertion is true, but Reason is false

D

Assertion is false, but reason is true

Text Solution

Verified by Experts

The correct Answer is:
B
A single speices may give rise to new speices (i.e. Intraspecific speciation) or two different species may give rise to a new species (i.e interspecific hybridisation) if intraspecific speciation occurs in geographically separated population it is termed as allopatric speciation if intraspecific speciation occurs in the population occupying the same geographical area, it is called sympatric speciation there are several factors involved in intraspecific speciation, but in all case gene flow within the populations must be interrupted
