Free ball python genetics calculator
Ball Python Morph Calculator
Add the genes each parent carries and see every morph the clutch can hatch, with the odds per egg. Hets, supers and the designer names are included. It runs on the same genetics engine as Lock and Lay, the free ball python breeding game.

What the clutch can hatch
Add a gene to either parent to see the odds.
How to read the results
Each line is one possible baby and its chance per egg. A clutch of six to eight eggs rarely matches the odds exactly: a 25% morph can hatch three times or not at all. Het means the baby carries one copy of a recessive gene and looks normal; 66% het means a normal-looking baby from two het parents has a two-in-three chance of carrying it.
The three kinds of ball python gene
Co-dominant genes such as Pastel, Mojave and Enchi show with one copy and make a super form with two. Dominant genes such as Spider and Pinstripe show fully with one copy. Recessive genes such as Clown, Piebald and Albino need two copies to show. See every gene for the details of each.
