WebMeiosis is defined as a type of cell division that explains the division of germ cells which includes two nucleus fissions. The two fissions of the nucleus namely meiosis 1 and meiosis 2, give rise to four sex cells called gametes. Each sex cell comprises half the number of chromosomes of the parent cell.

WebMeiosis is the great process that shuffles the cell's genes around. Plants do it, animals do it, and even fungi do it (sometimes). Instead of creating two new cells with equal numbers of chromosomes (like mitosis), the cell does a second division soon after the first. That second division divides the number of chromosomes in half. WebJul 17, 2024 · Interphase. Ed Reschke/Getty Images. There are two stages or phases of meiosis: meiosis I and meiosis II.
