Question

which process swaps genetic material between homologous chromosomes, leading to genetic variation? (1 point) ∘ crossing-over ∘ independent assortment ∘ cytokinesis ∘ replication

Explanation:

To solve this, we analyze each option:

• Crossing - over: Occurs during meiosis when homologous chromosomes exchange genetic material, creating genetic variation.
• Independent assortment: Refers to the random distribution of non - homologous chromosomes during meiosis, not the swapping of genetic material between homologous chromosomes.
• Cytokinesis: Is the process of cell division (cytoplasm division) after mitosis or meiosis, not related to genetic material swapping.
• Replication: Is the process of DNA copying, not the swapping between homologous chromosomes.

Answer:

A. Crossing - over
