Explanation:

1. Human somatic cells (like skin cells) have 46 total chromosomes, with 23 inherited from each parent.
2. Human gametes (egg and sperm cells) are haploid, meaning they carry half the chromosome number of somatic cells.
3. A zygote forms when a haploid egg and haploid sperm fuse, combining their chromosome sets.
