Question

0. Why a small population of surviving genes faces a greater threat of
extinction. Provide a suitable explanation from the point of view of genetics ​

Answer 1

#Answer

Smaller populations are at greater threat

of extinction as compared to large species. This is because less number of individual in smaller population imparts lesser changes in production of genetic variations. Lack of genetic diversity makes the smaller species more prone to extinction under any dramatic changes in prevailing environmental conditions.

On the other hand, large populations exhibit more genetic diversity on which evolutionary forces act upon to make it withstand any changes in surrounding.

Answer 2

Answer:

Smaller populations are at greater threat of extinction as compared to large species. This is because less number of individual in smaller population imparts lesser changes in production of genetic variations.
