Because human gametes are of two kinds, sperm (male) and egg (female). The two come together to make 1 cell called a zygote. That then replicates and creates all your other cells. 23 + 23 = 46. That's why!
Sex cells have half the number of chromosomes as the original cell, and are said to be haploid. In human sex cells there are 23 chromosomes.
The sex cells, or gametes, (egg and sperm) don't contain pairs of chromosomes. They each contain 23 singular chromosomes. When the egg and sperm combine, the resulting cell will have 23 pairs of chromosomes.
it compares by 50% or by half of chromosomes because there are 23 sex cells and 46 chromosomes
Each human skin cell has 46 chromosomes, which are organized into 23 pairs. This includes one set of 23 chromosomes inherited from the mother and another set of 23 chromosomes inherited from the father.

Cause body cells have twice the chromosomes a sex cell has Body cells have 46 chromosomes and sex cells have 23 chromosomes.
Sex cells have half the number of chromosomes as the original cell, and are said to be haploid. In human sex cells there are 23 chromosomes.
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.
Sex cells have 1/2 the number of chromosomes of a normal cell (23)
The sex cells, or gametes, (egg and sperm) don't contain pairs of chromosomes. They each contain 23 singular chromosomes. When the egg and sperm combine, the resulting cell will have 23 pairs of chromosomes.
Humans have 23 chromosomes in their sex cells.

23 chromosomes
Sex cells have half the number of chromosomes compared to regular cells. Regular cells in the human body have 46 chromosomes (23 pairs), while sex cells (sperm and egg cells) have 23 chromosomes each.
Human cells have 46 chromosomes (call that 2n, or 2 times n). Now then, if an egg cell + sperm cell = fertilized egg (which becomes a human), how many chromosomes do each have? An egg cell must have 23 chromosomes, and a sperm cell must have 23 chromosomes, because 23 + 23 = 46. When the egg (23) and sperm (23) combine to form a fertilized egg, this egg will now have 46 chromosomes. So human sex cells have n, or 23 chromosomes. If you mean to distinguish somatic chromosomes from sex chromosomes, then you have 22 pairs of somatic chromosomes plus one pair of sex chromosomes, for a total of 46 chromosomes.
