WebJan 11, 2024 · Summary. Meiosis is a process of cell division that reduces the chromosome number by half and produces sex cells, or gametes. Meiosis is divided into two parts: Meiosis I and Meiosis II. Each part is similar to mitosis and can be divided into the same phases: prophase, metaphase, anaphase, and telophase. WebSep 8, 2024 · Mitosis produces two genetically identical “daughter” cells from a single “parent” cell, whereas meiosis produces cells that are genetically unique from the parent and contain only half as much DNA.
