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, as it ensures that the offspring inherit the correct number of chromosomes from each parent.
* Humans have 46 chromosomes, organized in 23 pairs.
* Meiosis produces gametes (sex cells), which have 23 chromosomes each.
* When a sperm and egg cell fuse during fertilization, the resulting zygote has 46 chromosomes again, half from the mother and half from the father.
Therefore, meiosis is the process responsible for creating the sex cells with the appropriate number of chromosomes for sexual reproduction.
