23 in both Egg Cells and Sperm Cells.

It gives one of the gametes an extra chromosome and leaves the other gamete with one less chromosome.
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
Gametes only have one of each chromosome, whereas somatic cells have a pair.
There are half as many chromosomes in gametes than in normal body cells.
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.
Gametes, such as sperm and egg cells, have half the number of chromosomes found in somatic cells. Therefore, human gametes have 23 chromosomes each.
Since the gametes contain one half the number, the zygote will have to have the full number of 40.

People have 23 chromosomes in their gametes – 22 autosomes and one sex chromosome. This is the result of a process called meiosis, which halves the number of chromosomes in a cell to produce gametes with half the genetic material.
Nondisjunction during meiosis I and II can lead to an unequal distribution of chromosomes in gametes. This can result in gametes having an extra chromosome (trisomy) or missing a chromosome (monosomy), which can lead to genetic disorders in offspring.
