Web1 mar. 2024 · Interkinesis. Definition. noun. Interphase II, i.e. a short resting period occurring between meiosis I and meiosis II. Supplement. Meiosis is a specialized form of cell division that ultimately gives rise to non-identical sex cells. There are two successive nuclear divisions: meiosis I and meiosis II. Each of them has four major phases. Web5 nov. 2024 · What happens in meiosis I? There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced. light up xmas pin

http://www.biology.arizona.edu/CELL_BIO/tutorials/meiosis/page3.html WebMeiosis. Meiosis is used to make special cells - sperm cells and egg cells - that have half the normal number of chromosomes. It reduces the number from 23 pairs of chromosomes to 23 single chromosomes. The cell copies its chromosomes, but then separates the 23 pairs to ensure that each daughter cell has only one copy of each chromosome. WebIn Prophase I of meiosis, what happens to increase genetic diversity?
