Question

Which of the following is a major contribution of crossing over?

• A. Genetic variation
• B. Recombination
• C. Inheritance
• D. All of the above

Answer 1

Answer: (B)

Recombination

Crossing over is the phenomena in which there is an exchange of the genetic material between the two homologous chromosomes. This is known as the process of genetic recombination. The recombination is the process which is the major contributor of crossing over. Genetic variation is introduced due to this recombination event. Inheritance is the passing of the characters from one generation to the next. If there is genetic recombination, then the new characters are inherited to the next generation resulting in variation.

Thus, the correct answer is option B.
