JAGS in australia

[MisLis]

It's jag to jag matings that have the problems. Breeders still persist in the hope to produce a leusistic carpet but they have major neuroligical problems and usually die. That's why most jags are jungle, diamond , Irian Jaya and Bredli crosses, they show the Jag traits (pattern etc) but not the neuroligical probems.

at what point do you classify 'inbreeding the ****' out as. this is a topic i'm a little touchy about but no body seems to be able to tell me where it stops being 'line' breeding and becomes "inbreeding the **** out of' sorry to go a bit off topic, but these nuralogical disorders surely will become more prevellant in the future of designer morphs??

i think that the gtp situation just gives the green light to smugglers, if customs and npws couldn't care about all the gtp's smuggled in over the last 5 years, then i'm sure they won't care about a few mutant carpets that they can't prove were smuggled in. stop the scare campaigns, it's open slather when it comes to customs.

If you're sure customs won't care about a few mutant Carpets being smuggled in, then i'm sure you're wrong, very, very sure...

I only used those words to describe the american (and possibly the aussie) jag gene pool. which has to be reasonably limited.

There are some good threads on Morelia Pythons (an american reptile forum). If you do a search you will get an insight of the genetics. There is a thread where they talk openly about the problems. True Jags are het for leusistic, which seems to be the problem when het leusistic is put over het for leusistic. Hope this helps.

The Jag gene is a co-dominant trait. So the gene pool is unlimited.

The Jag gene has been bred out to just about everything possible, and Jag is rarely bred to jag as it results in dead offspring, so I don't know how you come to that conclusion.

 

[Kurto]

fair call. I don't want to take this thread to far off topic, but how limited would you say the american carpet gene pool is? is this not where the original jag showed up?

yeah, it does abit. but it doesnt cover snakes born without eyes due to inbreeding. namely a case that comes to mind with albinoes.
MIs Lis can you explain for me how the jag gene is co dominant and how this means it is unlimited? i'm not crash on genetics.

is that the same customs that identifies P.platurus as S.swaini. they haven't employed anyone competent lately, have they? give us a break, i don't think they'll bar up about jags, when they showed how spineless they are when it came to all the greens, hundreds of them. incompetent fools who deserve to be ridiculed and unemployed.

Ummm... no, that would be NSW DECC you're referring to.

I'm sure you've heard of customs, they're the ones who do all the big drug busts, as well as setting up sting operations to catch person's picking up smuggled GTP's from the Post Office etc...

To put it into a castly simplified context, a reccesive trait such as albinism needs a gene from both parents to show the trait, therefor the best way to get that trait to show is with inbreeding.

Co-dominant means that some of the offspring will show at least some of that trait, for example you could take a jag and breed it to a normal average unrelated coastal and some will be jags, some will show limited jag like traits and some will just look like a coastal. Therefor you can breed a jag to anything and come out with jags.

As I said, vastly simplified. Genetics is a highly complex subject.

They even put together a radio ad regarding wildlife smuggling!

Perhaps moreliainsanity should call the hotline; he can help keep our borders secure!

Is there any truth behind animals with Jag like traits, from Jag parents?? They should either be Jags or not Jags nothing inbetween unless we are talking about linked genes?

thanks disasterpiece. so, if that is the case, why are these particular jags so inbred to the point of a nuro disease?

It has nothing to do with inbreeding.

It means that when a Jag is bred with a Jungle, Bredli, Diamond, Murray Darling ( which from what I know has been done in the UK but not in the US yet, I could be wrong) That the Jag patterning will show in the offspring. Even though the original jags were bred in Europe from a coastal to coastal mating, the majority of Jags are crossed with these other carpets to produce the Jag traits but not the neuroligical problems.

 

[Renagade]

where is it from then?

It is possibly linked to the original mutation and has limited penetrance.

The problem comes when Jag Is bred to Jag (the ultimate out come is a leusistic carpet). Unfortunetly the out come is neurolgical prablems.
