If those two cells each contain one set of chromosomes, then the resulting cell contains two sets of chromosomes. Haploid cells contain one set of chromosomes. Cells containing two sets of chromosomes are called diploid. The number of sets of chromosomes in a cell is called its ploidy level.

It notes that only a small portion of the chromosome is depicted, emphasizing the overall challenge with all 46 chromosomes. The solution involves duplicating chromosomes in the S phase to create dyads, condensing them for easier separation through ATP and condensin proteins, and ensuring even distribution of sister chromatids to daughter cells.

It outlines the key stages of meiosis I, including prophase I with crossing over for genetic diversity, and independent assortment in metaphase I. The process results in two haploid cells with sister chromatids. Meiosis II then separates these sister chromatids, ultimately producing four haploid daughter cells, enhancing genetic variation through these processes.
