Random morph question

OK....I just got my first BP...a nice little male pinstripe...

I have been doing a truck load of reading on BPs and genetics...both from websites and books...already started a "want list" and started stashing away a little bit from each paycheck...LOL the addiction hit hard!!!!


Anyways my question is this...I remember reading a thread on here about 2 weeks ago talking about certain morphs rendering females sterile...another thread also mentioned that one gender or another shows stronger inheritance for a morph trait or two....

Rendering a specific gender I can understand (just finished a genetics course in uni)...I guess I am just looking for info on which morphs these issues refer to? I cant find the thread and don't remember the exact morph details...


Thanks!!

Here is what i know...
Desert females haven't produce.
Caramel Albino Females have problems with their eggs too.
Spider x Spider = Super Spider is Lethal.
So is the Champagne Spider & there are others but can't think of them now lol

Just a small correction...

Spider X Spider is not lethal.

no such thing as a super spider

Hm, yeah what's the super spider..?
The only thing I've known about is the sterile desert females.

Here are a few links; I think you were talking about the Banana's; If so you'd better start saving hard they're still very pricey for the average person but should come down in price alot in the next few years. I know I cant wait to start working with them but It's going to be awhile.:banana:

Exactly because they are...Lethal. Meaning they are born dead.

I'm pretty sure that's a hypothesis not a theory do I wouldn't just blatantly state it as if were a fact.

Spider x spider is not considered lethal. Sorry.
Spider is a dominant, there can be no super. Only a co-dom can create a super form.

Super is really tricky when herpers use it. It could mean an animal with an extreme appearance caused by two copies of a particular codominant mutant gene in a gene pair. Or it could mean an animal with two copies of a dominant mutant gene. The first is more common simply because dominant mutant genes are rare in snakes.

S = a spider mutant gene
+ = a normal gene
// = an homologous pair of chromosomes
S//+ = a gene pair made up of a spider mutant gene in one chromosome and a normal gene in the same location in the other chromosome.

A spider ball python has a S//+ gene pair.

S//+ x S//+ -->
1/4 S//S (homozygous spider, AKA super spider). Dead????
2/4 S//+ (spider appearance). Alive
1/4 +//+ (normal). Alive.

No one has reported a S//S ball python from a breeding test, so we do not know what an S//S ball python looks like. It may or may not look like a S//+ ball python. We know a S//+ ball python does not look normal. Until someone produces a S//S ball python, all we are sure of is that the spider mutant gene is not recessive to the normal gene. The spider mutant gene could be either dominant or codominant to the normal gene; nobody knows. When speaking about the spider mutant gene, dominant means "not recessive".

Yea what he said...

Like most of our "dominant" morph, spiders do not have a proven homozygous form, whether it is from it being lethal or just simply from a lack of trying, there is almost no hard evidence of anything and definitely nothing conclusive.

OP you may find this helpful http://www.owalreptiles.com/issues.php

awesome thanks!!

After the thread where that Tommy Rosati kid from Spokane posted all the misinformation claiming breeding results from thousands of spiders you can see how the ball python community is screwed up enough not to know if spider is co-dominant lethal or dominant just unproven 20+ years after the original spider.
