WebOct 27, 2024 · Definition. Prophase I of meiosis I is a process that involves five different stages during which genetic material in the form of alleles crosses over and recombines to form non-identical haploid chromatids. Prophase I is the first stage of meiosis I, followed by prophase II, anaphase I, anaphase II, metaphase I and metaphase II. WebPage 5: Meiosis Describe what happens during each of the stages of meiosis: Stage Description 1. Interphase At the end of interphase, as the cell prepares for meiosis, the chromosomes replicate.
