WebBut after G 2, the cell instead enters meiosis, which consists of two cell divisions, not one. The second cell division exists because the gametes to be formed from meiosis must be haploid. This is because they are going to join with another haploid gamete at conception to produce the diploid zygote. Meiosis is like a two-part made-for-TV ... WebMitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. They share some similarities, but also exhibit distinct differences that lead to very different outcomes (Figure 11.7). Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new cells. WebMeiosis creates 4 haploid daughter cells (gametes) from a diploid mother cell.

WebTo achieve the reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division. Because the events that occur during each of the division stages are analogous to the events of mitosis, the same stage names are assigned. WebMeiosis produces cells with half the number of chromosomes as the original cell. Haploid cells used in sexual reproduction, gametes, are formed during meiosis, which consists of one round of chromosome replication and two rounds of nuclear division. Meiosis I is the first round of meiotic division, while meiosis II is the second round. Key Terms hubsi biergartenWebSummary. OBJECTIVE Describe the details of meiosis. Cell division in reproductive cells is called meiosis. This two-phase process divides the chromosomes of a diploid germ cell, generating four haploid gametes.
