Question

Given below are two statements: Statement (I): Change in gene frequencies in erratic manner from generation to generation is called random drift. Statement (II): Random drift may lead to fixation or loss of entire genotypes in a population. In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Genetic drift is highly potent in small populations.
It causes random, erratic changes in allele frequencies that eventually result in complete fixation or loss of genetic diversity.

Answer 1

The Correct Option is A
