Meiosis is a type of cell division. It contains two successive cell division such as meiosis I and meiosis II. Each division results in two daughter cells, thereby, meiosis finally produces four daughter cells. Meiosis is involved in the production of gametes. During fertilization, two gametes are fused and produce a zygote, a single cell. Errors during the process of meiosis I or II can result in extra or missing chromosomes in cells. These errors occur infrequently and most of them may produce lethal effects. Nondisjunction in meiosis may lead to extra or missing chromosomal DNA.
