Each organism has a distinct number of chromosomes, in humans, every cell contains 46 chromosomes. Other organisms have different numbers, for instance, a dog has 78 chromosomes per cell.
Somatic Cells - body cells, such as muscle, skin, blood ...etc. These cells contain a complete set of chromosomes (46 in humans) and are called DIPLOID.
Sex Cells - also known as gametes. These cells contain half the number of chromosomes as body cells and are called HAPLOID
Chromosomes come in pairs, called Homologous Pairs (or homologs). Imagine homologs as a matching set, but they are not exacly alike, like a pair of shoes.
Diploid cells have 23 homologous pairs = total of 46
Haploid cells have 23 chromosomes (that are not paired) = total of 23
There are 46 chromosomes in a diploid (body) cell There are 23 chromosomes in a haploid, or gamete (sex cell)
23 Pairs
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.
The human sex cell or human gamete has half the number of cells that any other normal human cell would have. A normal human cell (the one from your skin, mouth, lung, liver, sex organs, etc.) has 23 pairs of chromosomes and as such are called diploid cells. The sex cells are haploid having only 23 number of chromosomes as they unite with another haploid cell to create a normal cell with complete set of 23 pairs of chromosomes. The 23rd chromosome on a male human gamete is either the X or the Y chromosome while on the female gamete it is always the X chromosome.
There are 23 chromosomes in a human sperm or egg (ovum).Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
Each cell has half the normal number of chromosomes and the cells are usually genetically different.- Iroda JuraevaEach cell has half the normal number of chromosomes and the cells are usually genetically different.

Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes. So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.
Each human cell has 23 pairs of chromosomes or 46 chromosomes.
There are 23 haploid chromosomes in a normal human gamete (sex cell).
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.

I assume you mean human egg and sperm cells. There is a haploid number of chromosomes in these cells. 23 chromosomes. n.

Gametes have half the number of chromosomes that most cells in the organism have. Most human cells have 46 chromosomes, but eggs and sperm have 23 chromosomes each.
There are 23 haploid chromosomes in a normal human gamete (sex cell).
