Solution

The correct option is C Assertion is correct but Reason is incorrect
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 gene 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.
So, the correct answer is 'Assertion is correct but Reason is incorrect'.
