How Are Seedless Watermelons Grown?

If you've enjoyed a delicious seedless watermelon, you might wonder how they are grown.
It starts by treating watermelon seeds with a chemical that makes the seed have 4 times the normal number of chromosomes. After planting, when this watermelon flowers, it receives pollen from a normal watermelon.
The result is a fruit that has few seeds....and even if it has seeds, they are crunchy and eminently edible.
