23, there are 23 chromosomes in human gametes
Humans have 23 chromosomes in their gametes, which are sperm and egg cells. This is half the number of chromosomes found in a somatic cell, which has 46 chromosomes.
Humans have 23 pairs of chromosomes, with 22 pairs of autosomes and one pair of sex chromosomes. During gamete formation, the chromosome number is halved, resulting in gametes with 23 chromosomes. Therefore, the organism that has 20 chromosomes in one of its gametes would not be human.
A human gamete contains 23 single chromosomes. Gametes are haploid cells, meaning they have half the number of chromosomes compared to diploid somatic cells, which contain 46 chromosomes. Each gamete, whether sperm or egg, carries one set of chromosomes, which is crucial for sexual reproduction. When two gametes fuse during fertilization, they restore the diploid number of chromosomes in the resulting zygote.
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.

In human gametes, chromosomes are not paired. Instead, each gamete has one set of 23 chromosomes, and is said to be haploid.
Humans have 23 chromosomes in their gametes, which are sperm and egg cells. This is half the number of chromosomes found in a somatic cell, which has 46 chromosomes.
Gametes, such as sperm and egg cells, have half the number of chromosomes found in somatic cells. Therefore, human gametes have 23 chromosomes each.
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
a human, gametes have 23. half the number of other cells
Normal human gametes carry 23 chromosomes, which is half the number of chromosomes found in a somatic cell. During fertilization, a sperm cell with 23 chromosomes fuses with an egg cell, also with 23 chromosomes, to form a zygote with a total of 46 chromosomes.
The gametes must have half as many chromosomes as normal body cells because they unite to form a zygote, which is the first body cell of the new organism. For example, human body cells have 46 chromosomes and human gametes (sperm and egg cells) have 23 chromosomes. When the sperm fertilizes the egg, the zygote will have 46 chromosomes, and is the first body cell of the new human.
I will assume that you mean human cells. Somatic cells are diploid (2n), containing two sets of chromosomes, one of paternal, one of maternal origin. Gametes, on the other hand, are haploid (n), with a single set of chromosomes, ie. half as many as the somatic cell. Now, the haploid chromosome number (n) is characteristic of the species, and in humans this number happens to be 23. Therefore a human gamete has 23 chromosomes, and a human somatic cell 23 pairs, or 46 chromosomes.
There are 23 in both a sperm and egg cell. These unite to form a zygote, which has 46 chromosomes.
Human gametes are haploid because they contain half the number of chromosomes as normal body cells. This allows for the fusion of two gametes during fertilization to create a diploid zygote with the correct number of chromosomes.
