Botany 101 Extra Female Chromosomes In Plants

Polyploidy is the state of a cell or organism having more than two paired sets of chromosomes.Most species whose cells have nuclei are diploid, meaning they have two sets of chromosomes—one set inherited from each parent.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.
