Here's why:
* Meiosis is a type of cell division that reduces the number of chromosomes in a cell by half. This is crucial for sexual reproduction because it ensures that the offspring inherit half of their genetic material from each parent.
* Sex cells (sperm and egg) only have half the number of chromosomes found in other cells of the body. This is why when a sperm and egg fuse during fertilization, the resulting zygote has the correct number of chromosomes.
