Homologous chromosomes may exchange segments; this is called crossing over. Crossing over increases genetic variability.

Question

Where would you add "crossing over" to the Venn diagram?
Responses
A MeiosisMeiosis
B MitosisMitosis
C Center - both mitosis and meiosisCenter - both mitosis and meiosis
D All three locations--crossing over may occur at any time during the cell cycle.

Answer 1

In the context of your question, "crossing over" specifically occurs during meiosis when homologous chromosomes exchange segments. Therefore, the most accurate choice for where to add "crossing over" in the Venn diagram would be:

A. Meiosis

This is because crossing over is a key event that contributes to genetic variability during the formation of gametes in meiosis and does not occur during mitosis.
