Although polyploidy is a frequent and recurrent phenomenon, the number of WGDs that have become established in What is Polyploidy? Humans are considered diploid organisms because we carry two sets of chromosomes (23 from each parent). There are other types of “ploidy”, however, including haploid (1 set), triploid (3 sets) and tetraploid (4 sets).

Polyploidy is the state of a cell or organism having more than two paired (homologous) sets of chromosomes. However, some organisms are polyploid, and polyploidy is especially common in plants. In addition, polyploidy occurs in some tissues of animals that are otherwise diploid, such as human muscle tissues.

There is nothing to say that an organism or a set of organisms unable to tolerate almost all polyploid events are therefore unable to survive all polyploid events.

Polyploidy refers to a condition in which a diploid cell or organism acquires additional sets of chromosomes. Although polyploidy is less common in mammals than in plants, polyploid cells are generated in different tissues. Polyploidy plays an essential role during normal development and could also contribute to human diseases.

Diploid human cells have 46 chromosomes each, but in cancer cells, this number may reach 100 or more due to abnormal divisions. In such condition, polyploidy, whether complete or mosaic, leads to gross abnormalities and death. Role or significance of polyploidy: Polyploidy in islets of normal and diabetic humans.
