WebMeiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. WebMeiosis 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.
WebMeiosis is part of the sexual process because gametes (sperm, eggs) have one half the chromosomes as diploid (2N) individuals. Phases of Meiosis There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell.
