Web27 okt. 2024 · 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. Web9 apr. 2024 · G 1 Phase (First Gap). The first stage of interphase is called the G 1 phase (first gap) because, from a microscopic aspect, little change is visible.
