Mitosis is making a replica with the same amount of chromosomes making it a diploid cell. Meiosis is when 2 sex cells unite and this makes a haploid cell. This is also what gives you 46 chromosomes. 5s 動線の確保WebMeiosis 2 is similar to mitosis because it separates the chromosomes to have sister chromatids in each cell. In both processes, you are separating the chromosome and dividing the cell to make 2 cells out of 1 (the only difference is that in meiosis, you're doing that for 2 cells to get 4). These are called daughter cells. 5s 動画教育
