* Somatic Cells: These are all the cells in your body except for reproductive cells. They are diploid, meaning they have two sets of chromosomes (one set from each parent). In humans, this means 46 chromosomes total.
* Gametes: These are your reproductive cells (sperm and egg). They are haploid, meaning they have one set of chromosomes. In humans, this means 23 chromosomes total.
Why the difference?
When a sperm and egg cell unite during fertilization, they combine their single sets of chromosomes to create a new individual with a full set of 46 chromosomes (23 from each parent). This ensures that the offspring inherits half of its genetic material from each parent.
In summary:
* Somatic cells: Diploid (2n), 46 chromosomes in humans
* Gametes: Haploid (n), 23 chromosomes in humans
