WebbMeiosis I. Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes.
