Here's why:
* Meiosis is a type of cell division that reduces the number of chromosomes in a cell by half. This is essential for sexual reproduction, so that when two gametes (sperm and egg) combine, the offspring has the correct number of chromosomes.
* Diploid: Body cells are diploid, meaning they have two sets of chromosomes (in this case, 10 total chromosomes).
* Haploid: Gametes are haploid, meaning they have only one set of chromosomes.
Therefore, during meiosis, the 10 chromosomes in the body cell are divided equally, resulting in two cells with 5 chromosomes each.
