Question

Random genetic drift in a population probably results from :

• A. Highly genetically variable individuals.
• B. Interbreeding within small population.
• C. Constant law mutation rate.
• D. Large population size.

Answer 1

The correct option is B Interbreeding within small population.

Interbreeding is the breeding between two different closely associated species where as intra breeding is the breeding among the same species.

Genetic drift can cause elimination of certain allleles or fixation of the other allleles in the population.

So, the correct option is 'Interbreeding within small population'
