Question

Random genetic drift in a population probably results from

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

Answer 1

The correct option is C Interbreeding within small population

Random drift or genetic drift occurs by chance and brings about change in gene frequency.

Genetic drift occurs in small populations and as a result of inbreeding leads to either loss or fixation of an allele.

b. Interbreeding within small population
