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.
WebMeiosis I divides the number of chromosomes in half, making the cell haploid. The homologous chromosomes divide. Each cell still has 1 of each type of chromosome (1 #1, 1#2, 1 #3, etc.) but only one of it. Note that 1 chromosome still has 2 sister chromatids, which are identical. Meiosis II divides the sister chromatids apart, still keeping the ... Web1 dag geleden · Figure 3: Nondisjunction results in daughter cells with unusual chromosome numbers.
