WebJan 22, 2024 · Unlike mitosis, meiosis involves two rounds of cell division. These happen across two stages: Meiosis I, and Meiosis II. Each stage of meiosis can be further divided into five phases: prophase, prometaphase, metaphase, anaphase, and telophase. Egg and sperm cells The Stages of Meiosis Meiosis I WebMEIOSIS Meiosis is a reduction division that divides the parental chromosome number by half and uses two divisions to produce four daughter cells; each with one copy of every chromosome. Meiosis occurs only in cells set aside for sexual reproduction. To divide the nucleus, meiosis consists of two consecutive phases called meiosis 1 and meiosis 2. …

Mitosis and … WebThe human body uses both meiosis and mitosis as methods of cell division. A single cell splits into two identical daughter cells during the process of mitosis, each of which has the same number of chromosomes as the parent cell. It takes place in somatic cells, which are the body's non-reproductive cells, and is in charge of growth and repair.
