During which step of meiosis does crossing over occur? A. prophase I B. anaphase I C. telophase I D. metaphase I

During meiosis, crossing over occurs during prophase I. It is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes, which contribute to genetic diversity.

It occurs at A. prophase, I say this because, most of the answers here aren't happening when it crosses over.
