I bought them from Ben in Replite Haven in Dublin, Ireland... he told me that they are and unrelated pair and they came via the UK from Paul Harris in Germany.

As I said... I don't know a whole lot about snakes... and am learning quite a bit from this forum... I have asked around and Ben seems to be probably the most respected guy in Ireland when it comes to reptiles... so I can only take him at his word... and I have no reason to doubt him at the moment!

Personally I can't see much difference between a jungle and an irian jaya in some pics... so I really am a complete novice and bow to people with greater knowledge on the subject (but its not hard to have more knowledge than me!)

So one may carry it and therefore be 100% het granite? but you wouldn't know till you breed probably more than once?
The other may not carry it so would just be normal Irian Jaya? so even mating with a 100% het granite would still produce normals? or would these then have the posibility of being het?

And if you had two 100% hets... would they always produce granites? or is there only a chance that they might produce granites?

Sorry for all the questions... it probably seems very basic to someone that knows what they are talking about... On an aside note and not wanting to change the topic of the forum... can you recommend a simple but kind of indepth and worthwhile book on carpets?
if one was het and the other wasn't you would get 50% hets and 50% normals. Again though because they would all look normal they would all be classed 50% hets. Obviously this is the breeding scenario yours came from, the breeder bred a normal to a 100% het.

Trouble is you would have to prodcue a visual granite to prove if either of yours was indeed het. If you put the 2 50% hets together, and get a visual granit you will know they are both 100% het. If you don't get any visual granits it doesn't really tell you anything, one or both could still be 100% het. Unless you are really really lucky you really need to breed to a visual granite to prove it out, that way if you don't get any visuals, you would have a pretty good idea it wasn't het, as missing the 50% odds of getting a visual would be very unlikely.

OK... I think I have a little grasp on it... and even if both were 100% het it doesn't necessarily mean that it would produce a visual with each offspring?

if they were both 100% het then each egg would have a 25% chance of producing a visual granite. So you would be a bit unlucky, but it is possible to have a clutch of all normall looking babies from a het - het breeding.

I don't understand why only 25%? Why would it not be 50% chance?

because you are dealing with 4 possible genes to make up a pair, the genes you have are

N = Normal G = Granite

they are in the following combination

Male = N - G
Female = N - G

Each animal passes 1 gene from its pair, giving the following possible combinations.

N - N = Normal
N - G = Het granit
G - N = Het granit
G - G = Visual granit

Normal 25%
Het 50%
Visual 25%

If you put a visual granit with a het you get 50% odds because you have the following combinations

Male = G - G
Female = N - G

G - N Het granit
G - G Visual granit
G - N Het granit
G - G Visual granit

Visual 50%
Het 50%
