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!

∙ 13y agoDuring the process of meiosis that sex cells undergo, the chromosome set is halved from 46 to 23 chromosomes. This way, the combined chromosome sets of two sex cells, the sperm and the egg(ova) after fertilization result in a full set again.

How many chromosomes are in their sex cells?
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.
How many matched pairs of chromosmes are there in each cells?
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.
How does the number in chromosomes in sex cells compare to the number of chromosomes in cells formed during mitosis?
it compares by 50% or by half of chromosomes because there are 23 sex cells and 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 non-sex chromosomes are in a human?
A somatic or non-sex cell has 23 pairs or 46 total chromosomes. Sex cells or gametes have a total of 23 chromosomes.
How are body cells different from sex cells?
Cause body cells have twice the chromosomes a sex cell has Body cells have 46 chromosomes and sex cells have 23 chromosomes.
How many chromosomes are in their sex cells?
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.
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 are sex cells different from other cell in the body?
Sex cells have 1/2 the number of chromosomes of a normal cell (23)
How many matched pairs of chromosmes are there in each cells?
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.

How many does a human sex cells have?
23 chromosomes
What types of cells contains 23 chromosomes?
Human sex cells.
How many chromosome are found in sex cell?
The number of chromosomes found in a sex gell depends on the organism discussed. The number of chromosomes in a sex cell is half the number found in the body cells. Human body cells have 46 chromosomes, their sex cells have 23.
