In which stage of meiosis does crossing over occur?

Understand the Problem

The question is asking for the specific stage in meiosis where the process of crossing over takes place. Crossing over is crucial for genetic diversity and occurs during meiosis when homologous chromosomes exchange segments of their genetic material.

More Information

Crossing over, which increases genetic variation, occurs specifically at the pachytene stage of prophase I.

Tips

A common mistake is confusing prophase I with prophase II; crossing over only occurs in prophase I.
