WebSep 4, 2024 · Crossing-over occurs during prophase I, and it is the exchange of genetic material between non-sister chromatids of homologous chromosomes. Recall during prophase I, homologous chromosomes line up in pairs, gene-for-gene down their entire length, forming a configuration with four chromatids, known as a tetrad. WebCrossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
