Question

Find the mis-match from the following pairs.

• A. Divergent evolution $\to$ Thorn from of bougainvillea and tendril of Cucurbita
• B. Adaptive radiation $\to$ Australian marsupials
• C. Natural selection $\to$ Industrial melanism
• D. Genetic drift $\to$ Constant gene frequency

Answer 1

The correct option is D Genetic drift $\to$ Constant gene frequency

• Genetic drift describes random fluctuations in the numbers of gene variants in a population.
• It takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.
• So, the gene frequency keeps on changing and is not constant.
• Thus, the correct answer is option D.
