Default Known and potential genetic defects in morphs!

After alot of recent discussion in the snake section i have decided to start a thread where people can list any known or possible genetic defects caused or associated with certain genes or potential pairings.
This is not a thread for debate over the rights and wrongs of such breedings but as information to help people with potential breeding pairings and/or purchasing a new snake.
If or when a solution to a problematic pairing occurs (i.e a super jungle produces a viable litter) feel free to add a link with supporting evidence and any additional information.
Cheers Stu

Ill go first with the ones i am aware of

Boa Constrictor Imperator;

Super Motley.
The Super motley is produced from a motley to motley pairing. Super motleys can be either Colombian or C.A.
So far there is no confirmed evidence either have survived long enough to produce a viable litter.The C.A Super Motleys seem to be stronger than the Colombian versions which to my knowledge have all either died before sexual maturity or are in the process of health deterioration to the point death seems likely.
The cause is thought to be underdeveloped muscles leading to a weak snake. At the moment it doesnt look as if any amount of outcrossing will help resolve the issues.


Super Jungle.
Super Jungles appear to be unable to reproduce,although more are now survivng into adulthood i have seen no reliable evidence of viable litters being produced.

Breeding Albino to Albino.

As far as im aware this is relevant to both Kahl and Sharp strains of Albino.
Not always but pairings of visual to visual albino has lead to litters of boas with deformities, particularly around the eyes.
The overiding consensus among boa breeders would be to breed none related visual to a het to increase the chances of producing healthy offspring.


Royal Pythons.

Spider Royal.

The spider gene is a co dominant mutation. It has been said that all royals carrying the spider gene will suffer from neurological issues described as "head wobble". This can very from being hardly noticeable to servere corkscrewing and starglazing. How much this effects the snakes quality of life is open to dispute, spiders are also said to be strong feeders and breeders.
I believe the super form of the spider gene to be lethal,no living Superspider has been produced.

Default royals

pearl - AKA super woma = fatal
add another gene to the mix, ie: lesser - and everything appears to be ok

caramel albino - certain lines carry a much higher percentage of kinked individuals than other lines

Extreme hypo honduran milk snakes
This morph seems to carry a leathal gene and enlarged heart issues.
I've actually tried to grow on 3 of these and all 3 passed around 6 months, and carried the same defect.
All were unrealted and UK, US And European lines.

Caramel corns and striped corns

Enlarged heart and sudden death,wittnessed in both morphs, weakness and prone to sudden weight loss.

ooh I didn't know that about caramel and striped corns!

One to add for leos, I assume this sticky relates to both snakes and lizards?

Enigmas -
Enigma syndrome is only found in enigma leopard geckos. Symptoms range from star gazing, circling, head shaking, head tilt, difficulty with co-ordination including hunting for food and at its most severe, death rolling. Most leos with enigma syndrome can be managed with a little extra TLC, however if a leo is death rolling the kindest thing is to euthanise. Enigma syndrome can be present from birth or develop at a later date. Enigmas showing this syndrome should NOT be bred from. It is also advised not to pair 2 enigmas when breeding even if the parents do not display enigma syndrome.

Good thread mate. I'll do more posts in here in time. For now...

Albino boas. The albino is a weak gene in that one eyed albinos can result from unrelated het x het breeding, albino x het breeding and worst of all albino x albino. No matter how much outcrossing has been done it doesn't have seemed to fix the problem. One eyed albinos can come from any pairing.

Super Aztec Boas: both Patternless Super Aztecs born in 2008(one died within a few month's from improper force feeding) from two different female Aztecs had or have the same problem as the Super Aztecs which can best be described as a lack of coordination. Several Super Aztecs including the remaining Patternless Super Aztec have seen improved coordination with age and a 2007 male Super Aztec produced a viable litter this year. Andrew Potts.

Leucistic Texas rat snake. Some lines have enlarged, protruding eyes (bugeyes). As some lines have normal eyes, the problem may be environmental. Pigs have congenital eye problems if the mother is somewhat deficient in vitamin A. Could this be the problem in LTRS too???

Keep in mind that Pearl is homozygous HGWoma, not homozygous Woma - the homozygous form of the Woma gene (which is not the same as HGWoma) does not look visually distinctive from a Woma and is not lethal, as per BHB.

There is an informative read regarding Super Jungle Boas/Arabesque boas and motleys problems and potential problems here:-
