select the correct statement about recombination.

genetic recombination occurs
when four daughter cells are
created after meiosis.

genetic recombination occurs
when one molecule of dna takes
pieces of their genetic material
from other.

genetic recombination only
occurs during mitosis.

genetic recombination occurs
when two molecules of dna
exchange pieces of their genetic
material with each other.

Explanation:

Genetic recombination involves the exchange of genetic material between two DNA molecules (e.g., homologous chromosomes crossing over in meiosis). The first option confuses recombination with the final product of meiosis. The second option incorrectly describes one-way transfer instead of mutual exchange. The third option is wrong because recombination does not occur in mitosis (which produces identical cells). The fourth option accurately defines recombination as mutual exchange between two DNA molecules.

Answer:

Genetic recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other.
