WebMeiosis I. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase, which is also called the first gap phase, is the first phase of the interphase and is focused on cell growth. The S phase is the second phase of interphase, during which the DNA of the … WebSignificance of meiosis. Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction; it is a significant chance to introduce genetic diversity into gametes.
