Humans have 46 individual chromosomes. Which translate into 23 pairs.Â
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
22 pairs of autosomes, one X-chromosome, and one Y-chromosome
The original cell (before meiosis occurs) will have a chromosome number of 2n. After meiosis, the resulting daughter cells will have a chromosome number of n. So the daughter cells will have half the number of chromosomes as the original cell. For example, a normal somatic (non-sex) human cell will have 46 chromosomes. Each gamete (the result of meiosis) will therefore have 23 chromosomes.
I believe the answer to your question is 23.
Oh, dude, the 2n chromosome number for skin cells is 46. Like, that's the normal number of chromosomes in a human cell, so your skin cells are just chilling with their 46 chromosomes, doing their thing. It's like the perfect number for a skin cell to be, you know?
Gametic [haploid] Cells are chromosome number n - which involves 23 individual chromosomes. Somatic [or diploid] Cells are chromosome number 2n - which involves 23 pairs of chromosomes. Mitotic Cells are 4n.
A normal human being has 23 chromosomes from each parent, giving them 23 pairs or 46 in total.

If the somatic (normal) cell has 38 chromosomes, then the diploid number will be 38. If the gametes (sperm and ovum/egg) have 38 chromosomes, then the diploid number will be 76.

A trisomy. Trisomies are usually fatal in all chromosome pairs except 5, 13, 21 (these cause Down syndrome), and 23 (The chromosome pair that determines gender)

Real human chromosomes consist of different number of base pairs. For example, chromosome 1 is the largest and contains about 249 million base pairs, while chromosome 21 is the smallest and contains about 48 million base pairs. In total, all 46 human chromosomes contain approximately 3.2 billion base pairs.

Every chromosome is a different size so the number of base pairs is different for each chromosome. X chromosome has more that 153 million base pairs (greater that 306 million bases) Y chromosome has around 50 million base pairs (around 100 million bases)
