Question

Linkage drag is the phenomenon in which:

• A. The undesirable genes also get transferred along with the desirable genes.
• B. Only the desirable genes from donor parent get transferred.
• C. The frequency of recombination between the desired and unwanted genes is increased.
• D. The unwanted genes are eliminated from the population.

Hint:

Understanding linkage drag is important for geneticists to develop strategies to break these linkages through breeding programs, enhancing desirable traits while minimizingunwanted ones.

Answer 1

The Correct Option is A

Linkage drag occurs when undesirable genes are linked to desirable genes on thesame chromosome and are consequently transferred together during breeding, affecting the overall quality of the resulting plants or animals.
