A common crop of natural autopolyploid grown is Potato.
Polyploidy is a condition in which the cells of an organism have more than one pair of (homologous) chromosomes.
Autopolyploids are polyploids with multiple chromosome sets derived from a single taxon.
Autopolyploids possess at least three homologous chromosome sets, which can lead to high rates of multivalent pairing during meiosis (particularly in recently formed autopolyploids, also known as neopolyploids) and an associated decrease in fertility due to the production of aneuploid gametes.
