WebMeiosis is a type of cell division that results in the creation of four daughter cells from a single parent cell. The process is called mitosis. The purpose of this type of cell division in sexual reproduction is to generate genetic diversity; it is … WebJul 5, 2024 · When changes occur in a cell that produces gametes, future generations are affected. Crossing-over When homologous chromosomes come together during prophase I of meiosis, they exchange bits of DNA with each other. This crossing-over results in new gene combinations and new chances for variety. WebOne purpose of meiosis is to reduce the number of chromosomes by half. The other is to create genetic diversity.
