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

How many pair of chromosomes do normal human cells contain?
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.
How many chromosomes are present in human sex cells?
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.
How many chromosomes do human egg cells and sperm cells have?
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.
How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
Which statement correctly describes the genetic makeup of the sperm cells produced by a human male?
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.

How are sex cells different from others human cells?
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.
How many pairs of chromosomes do each human skin cell have?
Each human cell has 23 pairs of chromosomes or 46 chromosomes.
How many chromosomes are in a normal human sex cells?
There are 23 haploid chromosomes in a normal human gamete (sex cell).
How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
Which statement correctly describes the genetic makeup of the sperm cells produced by a human male?
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.
Number of chromosomes in eggs and sperm cells?
I assume you mean human egg and sperm cells. There is a haploid number of chromosomes in these cells. 23 chromosomes. n.
How many chromosomes are in a sperm Cell?
32
If the number of chromosomes in the skin cells of an organism is 28 what is the number of chromosomes in the organisms egg cells?
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.
How many chromosomes are in a humans sex cells?
There are 23 haploid chromosomes in a normal human gamete (sex cell).
