WebMeiosis is a type of cell division that halves the number of chromosomes. There are eight stages of meiosis, divided into meiosis I and meiosis II. DNA is not replicated between meiosis I and meiosis II. Crossing-over, the independent assortment of chromosomes during anaphase I, and random fertilization result in genetic variation.
