Question

when does crossing over, which creates diversity, typically occur? prophase ii anaphase ii anaphase i prophase i

Explanation:

Crossing over occurs during prophase I of meiosis. Homologous chromosomes pair up (synapsis) and exchange genetic material (crossing over), which increases genetic diversity. Prophase II involves spindle formation, anaphase I is about homologous chromosome separation, and anaphase II is sister chromatid separation. None of these involve crossing over like prophase I.

Answer:

prophase I
