Recessive inherited Clown was produced by VPI in 1999. This example is the heterozygous example. This means that the animal has one copy of the Clown gene, breed to another heterozygous Clown, and you have a 1 in 4 chance of producing visual Clown Ball Pythons. If you breed visual Clown to Het. Clown, your odds are 1 in 2.
