Sophie [7]

Answer:

Human gametes should contain <u>23 </u>chromosomes each. This number would be considered the <u>haploid </u>number for humans. The symbol for this is <u>n</u>.

Explanation:

Gametes are an organism's reproductive cells. Female gametes are called egg cells, and male gametes are called sperm.

In most organisms, somatic cells (all cells except for gametes) are diploid, whereas the gametes tend to be haploid. Haploid cells have a single set of chromosomes, while diploid cells have two sets of chromosomes.

When it comes to human cells, somatic cells have 46 chromosomes. This means that each gamete has 23 chromosomes. This is called the haploid number and is marked by a lowercase <em>n</em>. This number refers to the total number of chromosomes found in a gamete (for human cells n=23).
