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 Jungles

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.

The Jaguar Carpet Python

The Jaguar morph is typically defined by the reduction in pattern, particularly along the back.

This trait also reduces the amount of dark pigment that the animal expresses giving it an overall lighter  more colourful look.
Being a Co-Dominant trait, the jaguar carpet python can be bred to a normal animal and produce approximately half of the clutch expressing the Jaguar trait. When two Jaguar Carpet Pythons are bred together they produce the Homozygous form called a Leucistic. Unfortunately This Leucistic carpet Python is a leathal gene and  most animals die at various stages of incubation and very few make to hatching which usually perish within a few hours .

The Jaguar trait carries a genetic  Neurological Disorder. This disorder does not generally affect the overall health of the animal. Symptoms of this Neurological Disorder come on a scale from not visable to Quite noticable. These Symptoms are expressed from poor co-ordination to the most extreme cases, corkscrewing. Cases of the disorder are usually shown when the animal is stressed.

The Jaguars here at Roger’s Reptiles have also been mixed with other morphs to produce quality animals. These mixes include, SXR Caramel jarguars, Lester Caramel Jaguars. They have also been selectively bred for particular traits such as Jungle Jaguars, which have increased yellow/gold colours.
