Question

Assertion:Genetic drift is the change in allele frequencies of a population

Reason: Genetic drift always takes place in the large populations.

• A. A and B both are true
• B. A is true, B is false
• C. A is false, B is true
• D. Both A and B are false

Answer 1

The correct option is B

A is true, B is false

Genetic drift is like other mechanisms of evolution of new species. The selection of a particular gene allele is not done by nature, rather it happens by accidents [elephant foot stamping on insect population] which in turn leads to selection of some genes though they may not produce a survival advantage.
