In humans, polyploid cells are found in critical tissues, such as liver and placenta. A general term often used to describe the generation of polyploid cells is endoreplication, which refers to multiple genome duplications without intervening division/cytokinesis.

Where are polyploidy found?

Polyploidy is the heritable condition of possessing more than two complete sets of chromosomes. Polyploids are common among plants, as well as among certain groups of fish and amphibians. For instance, some salamanders, frogs, and leeches are polyploids.

Is polyploidy common in island groups?

Whole genome duplication or polyploidy is widespread among floras globally, but traditionally has been thought to have played a minor role in the evolution of island biodiversity, based on the low proportion of polyploid taxa present.
