Human gametes have 23 chromosomes.
(In cases of abnormality there may be a different number of chromosomes in a gamete).

If all of the chromosomes fail to separate in meiosis, then nondisjunction can result in a diploid gamete. This is a type of chromosomal mutation. In animals, a zygote produced from the union of a mutated diploid gamete and a normal haploid gamete will have triploidy, which is lethal. In plants, this is not necessarily lethal.
It varies from organism to organism. Humans have 23 chromosomes in a haploid (gamate) cell.
4. Two gametes get together to make something new. Just double up!
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.
39 chromosomes in each gamete
23 chromosomes
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.

There are 23 chromosomes in a human gamete
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.
Each gamete has only 23 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.
Sperm cells, or gametes normally have 23 chromosomes each.
There are 8 chromosomes in an onion egg (or gamete) cell.
