Assertion: Founder effect may lead to formation of new species.
Reason: Founders carry all the parental gene pool to a new location.

Text Solution

Verified by Experts

The correct Answer is:
C
When a few individuals or a small group of individuals from some large population invades a new or isolated geographical region, these become the founders or founder members. These founders carry on a limited portion of the parental genen pool. Their gene pool may contain certain alleles in a very low frequency or may lack a few alleles. the descendants of the founder i.e,. the founder population or marginal isolates in a new area will tend to have ratios similar to the founders rather than the source population. Sometimes they form a new species.

Fill up the balnks in the following paragraph by selecting the correct option. When migration of a section of population to another place and population occurs, I change in the original as well as in the new population new genes/ alleles are added to the ii, population and these are lost from the population. These would be a iv if this gene migration, happens multiple times. if the same change occurs by chance, it is called v. sometimes the change in allele frequency is so different in the new sample of population that they become a diffrent species. The original drifted population becomes founders and the effect is called vi
