Question

Genetic drift is :

• A. Gene frequency in same generation.
• B. Appearance of recessive genes.
• C. A sudden change in gene frequency from one generation to next.
• D. None of the above.

Answer 1

Answer: (C)

A sudden change in gene frequency from one generation to next.

Genetic drift is a sudden change in the frequency of an existing gene in a gene pool of a species, transmitted to the next generation, could occur due to a drastic change in the environment, an accident that may result in abundance of a particular allele type.

So, the correct answer is 'A sudden change in gene frequency from one generation to next'
