WebbDescribe the steps of meiosis 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 ... Webb10 apr. 2024 · Meiosis is the process of producing gametes—sex cells, or sperm and eggs in the human body. In a human being, the haploid cells made in meiosis are sperm and eggs. At the point when a sperm and an egg participate in fertilization, the two haploid arrangements of chromosomes create a complete diploid set: another genome.
