Question

Identify the process in which there is an exchange of genetic material between homologous chromosomes.

• A. Genetic recombination
• B. Gametogenesis
• C. Genetic drift
• D. Crossing over

Answer 1

The correct option is D Crossing over

Answer is option D i.e. "Crossing over"
Crossing over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. During crossing over the chromatids of the homologous pairs "cross over" and swap genetic material.
While, Genetic recombination is the process of recombining genes to produce new gene combination. Gametogenesis is production of gametes. Genetic drift means random changes in allele frequencies.
