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. This type of cell division occurs as ... WebThe production of gametes is a crucial process for sexually reproducing organisms. Meiosis is the mechanism used to reduce diploid cells to haploid gametes while introducing genetic diversity.
