The Albino Carpet Python first originated in Top End carpet Pythons (Morelia spilota variegata). The mutation is Recessive in nature and causes the production of browns and black pigments to be cancelled.
The result being a python that has bright shades of orange, yellow and whites.
Being the mode of inheritence of recessive, for the animal to express the trait visually, it needs to inherit the mutant gene from both parents.
Here are some of the Albino Carpet Pythons that are currently at Roger’s Reptiles.
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.
