Here's why:
* Somatic cells are diploid, meaning they have two sets of chromosomes (one from each parent). In humans, this means 46 chromosomes.
* Gametes (sperm and egg cells) are haploid, meaning they have only one set of chromosomes. This is because when two gametes fuse during fertilization, they create a diploid zygote with a full set of chromosomes.
Therefore, each gamete receives 23 chromosomes after meiosis.
