Axanthic color morphs are a exciting new addition to pure Jungle Carpet pythons. Typically they lack yellow pigment which gives them a black and white or greyish coloration as adults . Axanthic neonates upon hatching can show a light bluish color on the head and tail . As far as I know of there is only one source of Recessive Axanthic Jungle Carpet Pythons in Australia originating from one bloodline.
This particular bloodline of Jungle Carpet python produced 2 separate Black & Yellow breeding pairs that when bred together produced Black & White or Axanthic looking offspring in 1/4 of their clutch, the rest of the siblings in the clutch turned out to be B&Y colored jungles.
The Axanthic Jungle Carpet python adults I have now came from these Black and Yellow Jungles that were het for Axanthic ….
One of these B&Y breeding pairs had the same result several years in a row…. I.E. 1/4 B&W and 3/4 B&Y offspring . Confirming the B&W color in the 1/4 of the clutch were consistant ratios each year. Then a pair of these B&W jungles from this line were bred together, all offspring were B&W or Axanthic……Confirming the B&W Axanthic color trait was recessive in its mode of inheritance and descended from the B&Y jungles that were het for Axanthic, i.e. , the grandparents..
The other Black & White jungles we have here in Australia are the Julatten locality color phase . Although they appear superficially similar and the Julatten jungles do look Axanthic , their mode of inheritance is Polygenic. B&W Julattens are bred to each other to produce more B&Ws. Then fine-tuned by selective breeding to create nicer looking individuals.
I am expecting another clutch of Axanthic Jungle Carpet Pythons to hatch in December 2013.
