First Meiotic Division (Meiosis I / Heterotypic Division)

During the first meiotic division, a diploid cell divides to give two haploid cells — the chromosome number in each daughter cell is reduced to half of the parent cell's number, which is exactly why this division is called the heterotypic division. Like mitosis, it consists of prophase-I, metaphase-I, anaphase-I, telophase-I and cytokinesis-I — but prophase-I is dramatically more elaborate than mitotic prophase, because it is here that all the events unique to …
