Our Mutations

One of the most exciting things as a reptile breeder is being able to selectively breed for a desired outcome and then witness the new designer animals pop out into the world. Here @ Reptile Connexion we strive to produce genetically viable and robust designer mutations (morphs) using proven animals of a genetic trait and mode of inheritance. This mutations section has been created for two (2) primary reasons:
1. Visualisation: Display the mutations we currently have in our collections by showing proven results; and
2. Education: Describe how reptile genetics works, the genetic makeup of our mutations, and explain what to look for when you the reader wish to breed any of these genetic combinations.
Some of the mutations we are using in our breeding projects to date are:
Antaresia: Ghost, Tyrosinase-positive (T+) albino, striped, hypermelanistic, and hypomelanistic.
Morelia: Axanthic, Hypomelanistic, Albino, Jaguar, and Zebra.
Stay tuned for some exciting projects to be revealed, and dedicated pages of each mutation created.

Ghost Childreni

The Ghost Childreni Morph

Damian Hyde, Reptile Connexion.com, July 2012
The genetic makeup of the mysterious Antaresia childreni Ghost morph is limited and undocumented. The time has come for me to document my theories and experience within my own collection through feeding, keeping and breeding these underestimated animals over the past 6 seasons. Many Antaresia breeders have dismissed my theories over the years, and because of this I have therefore not discussed my thoughts to anyone outside of my close group of herpetoculture friends.
I have been out crossing and line breeding the ghost childreni since 2006 and am now starting to achieve some very interesting results.
I am convinced that there is more than one mode of inheritance involved when it comes to the expression of the Ghost phenotype.
An incomplete dominant hypomelanistic gene – A pairing between a Wild type Antaresia childreni and a Ghost Antaresia childreni will result in a percentage of a clutch expressing a reduced amount of melanin. These animals undergo subtle colour changes and display atypical shades of grey blotching instead of the standard black blotching. See attached photos of these animals that display the variation of their grey colour and patterning.
An ontogenic polymorphic colour change – A pairing of Ghost to Wild type animals will produce approximately 75% ghosts, they are not all visible till later in life – usually at 10+ months of age and in the first generation. Breeding siblings to each other or the parents will yield approximately 75% of the clutch expressing more predominant ghost traits after their second and third slough cycles.
Another observation that I have witnessed with the Ghost gene, is the colour hue changes of the animal at varying times. Originally it was perceived that the colour change was trigger by day to night, I have however observed that the time of day for colour transformation is irrelevant. I am still to determine what the triggers are; however I believe it is more related to heat, and digestion. When the ghost subjects get to the preferred body temperature (approx 28ºC) they will display lighter shades and variations, opposed to the darker variations when their body temperatures are below 26ºC. They also appear to change to their darker colour expression for about 20-24 hrs after consuming a prey item if offered to them during they lighter colour period. My interpretation of this phenomenon is that as darker colours absorb heat quicker, this potentially allows the animals to increase their body temps more rapidly therefore increasing their rate of digestion.

The first Super Ghost morph was created in 2009 by pairing two visual hets of the Ghost childreni mutation. The suspected Super Ghost was created from the original ghost F1 female, paired to a F3 male. This female Super Ghost is currently producing her own progeny and had 3 surviving hatchies from last season (2011). In 2013 I am looking forward to breeding a male back to the original mother.
This Ghost gene is now being utilised to create some very interesting morphs. I have been concentrating on selectively breeding these ghost childreni for approximately 5 years, and am now observing these changes more frequently! I also have a more informed understanding of the mutation due to an increase in the numbers of individual animals in my collection.
