Known Genetic Defects?

[Joppsta]

I found this list:

List of genetic defects/mutations in reptile morphs (from research on the internet, so some things may not be true):

BALL PYTHONS
Spider genes: any spider morph ball may suffer from mild to severe wobbles and thought to be lethal in homozygous form (doubling of the gene).
Woma and Hidden Gene Woma: Wobbles
Champagne: Wobble
Super Sable: Wobble
Powerball: Wobble
Sable x Spider: severe wobbles and difficulty hatching
Champagne x Spider: Lethal gene
Spider x Woma: Lethal
Champagne x Hidden Gene Woma: Severe Wobbles
Pearl: often times lethal
Super Champagne: lethal
Desert: fertility issues in the females
Caramel Albino: lower fertility in females and kinking
Super Cinnamon/Super Black Pastel: Duckbill and more rarely kinking
Super Lesser Platinum/Super Butter: bug-eyes
Lesser Platinum x Piebald: Small eyes
Banana/Coral Glow: the males may produce weird gender ratios
Albino: Associated with eye problems, inbreeding, and perhaps lowered immunity.
Blue Eyed Lucy: they may develop bug-eyes
Lavender: in some blood-lines their may be kinking

However that post was dated 2016 and I am just wondering if this is a comprehensive list. Saves people that are new to the hobby hitting landmines if they have basic Google skills.

I have to disagree

Blue Eyed Lucy: they may develop bug-eyes

Yes but not all, it concerns Super Lesser and Super Butter, not Super Mojave, or Lesser Mojave or Super Russo

Lavender: in some blood-lines their may be kinking

I disagree too


As for a list I would rather go by this one http://www.owalreptiles.com/issues.php

This is the first time I've seen Spider x Woma is lethal. Is that accurate? I've never seen a Spider Woma, but wasn't sure if lethality was confirmed.

According to Kevin at NEW ENGLAND REPTILE'S spider to spider isn't lethal!

There has never been a live one. They are not viable. You may be looking at old information.

To be a bit pedantic I think that would be better phrased as " Nobody has seen a viable, prove-able homozygous spider"

[JodanOrNoDan]

LOL. You sir are of course correct. I have not seen that word for awhile (pedantic).

It is next to impossible to prove something does not exist. I think statistically however we can say a viable (hobby terms) Super Spider, especially since we now know the mutation acts like a co-dom, has not and will not be produced.
