=== Polyploidy ===
[[Polyploidy]] can be induced to modify the number of chromosomes in a crop in order to influence its fertility or size. Usually, organisms have two sets of [[chromosome]]s, otherwise known as a [[diploidy]]. However, either naturally or through the use of chemicals, that number of chromosomes can change, resulting in fertility changes or size modification within the crop. [[Seedless watermelon|Seedless watermelons]] are created in this manner; a 4-set chromosome [[watermelon]] is crossed with a 2-set chromosome watermelon to create a [[Seedless fruit|sterile (seedless) watermelon]] with three sets of chromosomes.
