WebMeiosis I. Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes. WebAnaphase definition, the stage in mitosis or meiosis following metaphase in which the daughter chromosomes move away from each other to opposite ends of the cell. See more.
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 ... http://www.biology4kids.com/files/cell2_meiosis.html
WebMeiosis. Crossing over takes place between the chromatids of homologous chromosomes. Meiosis is a special type of cell division. Unlike mitosis, the way normal body cells divide, meiosis results in cells that only have half the usual number of chromosomes, one from each pair. For that reason, meiosis is often called reduction division. Webmeiosis a type of nuclear division associated with sexual reproduction, producing four HAPLOID (1) cells from a single DIPLOID (1) cell, the process involving two cycles of division. Although meiosis is a continuous process it has been divided into numerous stages, given below.
