Ordering the steps of meiosis
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. WebThe initial step of Meiosis 1 is Prophase 1, which takes place in a similar manner to Prophase in Mitosis. The genes get dense and move towards the central portion of the cell. ... Since while the alleles are lined up against the metaphase plate, there is no order of alignment of maternal and paternal plates. As a result, each allele has an ...
