Webb1 maj 2024 · Meiosis definition. Meiosis is a type of cell division in sexually reproducing eukaryotes, resulting in four daughter cells (gametes), each of which has half the number of chromosomes as compared to the original diploid parent cell.

Webb18 aug. 2024 · Meiosis is the type of cell division used to produce gametes or sex cells (sperm and egg cells). A cell undergoing meiosis will divide twice - the first division is meiosis I and the second is meiosis II. In the first meiotic division, the number of cells is doubled, but the number of chromosomes is not.

WebbLike the usual mitosis, the first meiotic division is divided into four different stages: prophase I, metaphase I, anaphase I, and telophase I. Meiosis I Stages (Source: Wikimedia) Prophase I. By far, prophase [4] I of meiosis is considered as the most complicated step in the whole process. Webb"The key to understanding the difference between mitosis and meiosis is not in the steps, but in the final products of each," says Brandon Jackson, assistant professor in the Department of Biological and Environmental Sciences at Virginia's Longwood University.

When you break it down it's just two PMATI's in a row. Scientists say Meiosis I and Meiosis II, but it's just two PMATIs.
