Question

Gene flow is described as

• A. The transfer of genes between populations which differ genetically from one another but can interbreed.
• B. The exchange of genes from the female to male organism.
• C. The transfer of genes from sperm to the egg.
• D. The transfer of genes from the nucleus to the chromosomes.

Answer 1

Answer: (A)

• Gene flow refers to the movement of genes from one population to another by interbreeding between individuals of the two populations.
• Since these populations have different gene pools, gene flow causes the movement of genes from a gene pool of one population to that of other. It plays an important role in evolution.

So, the correct answer is option A.
