I don't know if this holds true for Ball Pythons but last month at the Orlando FIRE show I watched a venom ecxtraction. The man doing the extractions (cant remember his name he owns a vemon facility in Deland FL) was talking about Parthenogenesis in florida cotton mouths.

In 1991 he collected an adult female florida cotton mouth from a ditch in volusia county. This snake was on their venom line in a rack type system alone for 11 years. In 2001 it gave birth (florida cotton mouths have live birth) to 3 male babies. Two of them were normal color phase and one has a luescistic apperance.
This snake has produced parthenogeneticly 3 times since then with all of the babies being male.
I thought this was pretty cool, so if you can incubate those eggs and see if they are fertile!
