This article will provide a detailed … WebMEIOSIS Meiosis is a reduction division that divides the parental chromosome number by half and uses two divisions to produce four daughter cells; each with one copy of every chromosome. Meiosis occurs only in cells set aside for sexual reproduction. To divide the nucleus, meiosis consists of two consecutive phases called meiosis 1 and meiosis 2. … WebFour haploid daughter cells are produced at the end, unlike two diploid daughter cells in mitosis.
