WebSince chromosome number gets halved, it is also called reductional division. 1. Meiosis is a process that gives rise to a haploid cell from a diploid one. 2. Haploid cell is the one that has a single set of chromosomes. While diploid cells have a double set of chromosomes. 3. Body cells are examples of diploid cells. 4. WebThe interphase is divided into three phases; G 1 phase, the cell grows in size and makes necessary proteins in this phase. S phase, the cell undergoes DNA replication. G 2 phase, the cell makes proteins that are needed for meiosis. After the G 2 phase is complete, the cells enter Prophase I.
