GAMETE
An organism with one set of chromosomes is called haploid. Haploid organisms have half the usual number of chromosomes, meaning they have only one set of chromosomes instead of the usual two sets (diploid). Examples of haploid organisms include certain fungi, algae, and gametes (sperm and egg cells) in animals.
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.

A sex cell is haploid, having one set of chromosomes, which is half of the number of chromosomes as in a body cell.
An amphidiploid is an organism with a diploid set of chromosomes from each of its parents.
This is called the organism's karyotype.
Haploid chromosomes are single sets of chromosomes found in the reproductive cells of an organism. In humans, haploid cells are created through the process of meiosis, where each parent donates one set of chromosomes to the offspring. Haploid cells have half the number of chromosomes as diploid cells, which contain two sets of chromosomes.
20 chromosomes
2n= 24 therefore one set consists of 12 chromosomes.
Sex cells called gametes have only one set of chromosomes, containing half the number of chromosomes found in other body cells. This allows for the fusion of two gametes during fertilization to create a new individual with a complete set of chromosomes.
When a zygote is diploid it obtains two sets of chromosomes. Gametes contain one set of chromosomes. Therefore, 6 chromosomes would amount to 3 sets of gametes.
A tetraploid organism has four sets of chromosomes, denoted as 4n. Since a haploid set contains one complete set of chromosomes, a tetraploid has four haploid sets. Therefore, a tetraploid (4n) has four haploid sets (n).
