The Het Red Axanthic Ball Python is a colour and pattern altering mutation whose name causes much confusion within the hobby. The term “het” is normally used in the hobby as shorthand for heterozygous while usually referring to a non-visual, single gene form of a recessive trait. Whereas HRA is an incomplete dominant trait, with the “Super form” being named the Red Axanthic.

While technically Het Red Axanthic is its heterozygous form, and Red Axanthic is the Homogenous, the shortened term “het” is used nearly entirely when talking about recessive traits.

In 2001, Corey Woods did a Black Back x Black Back pairing, hoping to produce more Black Backs.
When the clutch pipped, he noticed two of the hatchlings had purple heads and had an axanthic look to them in comparison with the rest of their siblings. [2]

HRA Ball Pythons have a dark head colouration, ranging from chocolate-brown to almost black.


This gene is characterized by its black back marking, keyhole-shaped alien heads, bold alien eyes, and white outlining of the alien heads near the belly. Flaming will also be present around the ring-shaped alien heads.


The tail of the HRA Ball Python usually carries the same “ring” pattern as its body.
