there are 23 chromosomes in a human gamete

The gamete is supposed to join with another gamete, and combine their chromosomes into a single cell.

Gametes normally contain only one set of chromosome – this number is called Haploid.

Gametes (sperm and eggs) contain only one sex chromosome.
To exhibit monosomy in a zygote, one gamete must contribute only one copy of a chromosome instead of the normal two. Therefore, if one gamete has a missing chromosome (e.g., due to a nondisjunction event leading to a gamete with 22 chromosomes instead of 23), it will result in a zygote that has only one copy of that chromosome when fused with a normal haploid gamete. In summary, the gamete with the missing chromosome (monosomic) is responsible for the resulting zygote exhibiting monosomy.
Gametes only have one set of each chromosome pair so that when two gametes come together, the chromosome number in the embryo is correct. There are 19 autosomes and one sex chromosome in the mouse gamete.
They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).
