WebTo achieve this reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division. Because the events that occur during each of the division stages are analogous to the events of mitosis, the same stage names are assigned. Web- meiosis to make 4 cells that have 1/2 the number of chromosomes as the original - lots of variety - diploid to haploid (pairs to singleton copies) (2n and n) What are the phases of the cell cycle? interphase, prophase, metaphase, anaphase, telophase (cytokinesis) IPMAT What's happens in Interphase? - most of the cell cycle (90%)

WebMeiosis is sometimes called "reduction division" because it reduces the number of chromosomes to half the normal number so that, when fusion of sperm and egg occurs, baby will have the correct number.

This first step is further subdivided into four main stages: prophase I, metaphase I, anaphase I, and telophase I. WebThis reduction in chromosome number is accomplished by two sequential rounds of nuclear and cell division (called meiosisI and meiosis II), which follow a single round of DNAreplication.
