Sperm cells, or gametes normally have 23 chromosomes each.

A gamete has half the number of chromosomes of the somatic (diploid) cell. Therefore a zebra gamete would have 25 chromosomes if 50 is the diploid number.
A gamete would be haploid, containing half the number of chromosomes compared to a diploid cell. Therefore, a gamete of this organism would be expected to contain 29 chromosomes.
Gametes carry half the number of normal chromosomes as a body cell. Since there are normally 46, this means there are 23 chromosomes in a human gamete.
23 chromosomes
Human gametes have 23 chromosomes. (In cases of abnormality there may be a different number of chromosomes in a gamete).

In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.
It varies from organism to organism. Humans have 23 chromosomes in a haploid (gamate) cell.
There are 23 chromosomes in a human gamete
Each gamete has only 23 chromosomes
A Drosophila gamete has 4 chromosomes. Drosophila, also known as fruit flies, have a diploid number of 8 chromosomes in their somatic cells, which means each gamete will have half of that number.
A gamete has half the number of chromosomes of the somatic (diploid) cell. Therefore a zebra gamete would have 25 chromosomes if 50 is the diploid number.
In a human cell we should have 46 chromosomes in 23 pairs. We get 23 of these chromosomes from the male gamete (sperm) and the other 23 from the female gamete (egg).
