WebMar 24, 2011 · The two-stage process of meiosis begins with meiosis I, also known as reduction division since it reduces the diploid number of chromosomes in each daughter cell by half. This first step is further subdivided into four main stages: prophase I, metaphase I, anaphase I, and telophase I. WebDuring meiosis one cell divides twice to form four daughter cells.
