Which three processes are methods of genetic recombination?

A. Natural selection, crossing over, and independent assortment

B. Crossing over, independent assortment, and fertilization

C. Independent assortment, fertilization, and natural selection

D. Fertilization, natural selection, and crossing over

Answer

The correct answer to the query is B. Crossing over, independent assortment, and fertilization.

Explanation:

Genetic recombination refers to the process by which genetic material is shuffled and rearranged to create new combinations of genes. The three methods of genetic recombination mentioned in option B can be explained as follows:

Incorrect Options:

A: While crossing over and independent assortment are methods of genetic recombination, natural selection is not a method of recombination; it is a process that affects which traits become more common in a population.

C: This option includes fertilization, but independent assortment and fertilization are not direct methods of recombination; they are related processes.

D: Similar to option C, this option includes natural selection, which does not contribute to genetic recombination.

Thus, option B accurately lists three methods of genetic recombination: crossing over, independent assortment, and fertilization.
