Web17 jul. 2024 · Interphase. Ed Reschke/Getty Images. There are two stages or phases of meiosis: meiosis I and meiosis II. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. At the end of the meiotic process, four daughter cells are produced. G1 phase: The period prior to the synthesis of DNA.

Web21 mrt. 2024 · During interphase, the cell grows to the size it needs to in order to divide, making copies of its various elements in distinct steps along the way. The end of the G 1 phase is signaled by a protein, marking what is called a G 1 checkpoint. A similar G 2 checkpoint marks the start of the M phase. There is no S 1 checkpoint, however. WebThe numbers of chromosomes is the DNA content are the same as in the female, however their are only 9 arms (the C value is effectively the same). The karyotype is described as 2N=6, XY. At this stage, the number of chromosomes equals the number of chromatids, and these are the same between males and females. When this cell undergoes mitotic ...
