In humans, all cells except gametes (sperm and egg cells) are diploid. This means they contain two sets of chromosomes, one from each parent.

Here's a breakdown:

* Diploid cells:

* Somatic cells (all cells except gametes) like skin cells, muscle cells, nerve cells, etc.

* These cells have 46 chromosomes arranged in 23 pairs.

* Haploid cells:

* Gametes (sperm and egg cells)

* These cells have 23 chromosomes, one from each pair.

When a sperm and egg cell fuse during fertilization, they combine their chromosomes to form a diploid zygote with 46 chromosomes. This zygote then develops into a human being.
