Blue Tree Python?

I was looking through google at green tree pythons and I saw this come up.
I've never seen this before. Has anyone eles?

high blue green tree pythons are a type of selectivley bred morph of the species.

like a ball python morph but with different type of genetics.

also some female GTPs may turn blue during breeding through egg laying and some may even keep the their new colours and stay blue.

Julian stated it well.
The first genetic form he mentioned doesn't seem to breed true. THe breeders working with those lines feel it may be polygenic but as far as I know they're not sure. I could be wrong, I haven't been paying attention lately.
And the second form he mentioned is called hormonal blue.

The mother of my chondro was a solid blue snake! If you look through the threads i started you can see my baby.:gj: I can get pics of the mother if you like.

its a beautiful blue frost gtp.

I heard thats what happens when they're hormonal...

some female GTPs turn blue while breeding and being gravid and when that happens its called "hormonal blue". some lucky breeders will have females that keep this blue colour permenantly after the breeding season although some may change back to their original colour.

breeding two blue GTPs will not guarantee you hatchlings that will grow up into blue adults but blue GTPs are selectively bred because the chance of getting GTPs that will grow up into blue adults is greatly increased.

its not a simple recessive gene and GTPs mature colours can be very unpredictable so youre not guaranteed blue adults but blue breeders increase the chances of blue offspring. like mike said, its a polygenic characteristic, so its not as predictable as recessive or dominant genes.

From what I understand there are 3 types of blue chondros, hormonal blue, blue, and super blue.

Hormonal blue is what happens when an adult green female turns blue as a result of breeding and producing eggs. These females sometimes retain some or all of their blue coloration after laying eggs.

Blue is when a male or female chondro gains blue scales after turning green first when changing colors as it grows, for example, from a red hatchling to green, then to blue, or from a yellow hatchling to green, then to blue.

Super blue describes animals that change directly to blue from their hatchling color without turning green first.

Yes my GTP has blue markings!!!:D

I always wanna see your pictures bro :gj:

Trooper Walsh is the man known for the blue line. TW and AZ paired up to make this color appear. They ended up with Mister Blue, there is also Carolina Blue. These are said to be the starting points for the blue line. Getting any descendant from one of these is going to be pricey. For some amazing blue snakes please check out BJarboreals.com which host MY personal favorite, Skyy.

You can take you chances (and they really aren't that bad) on buying a blue line baby. It might look just like a super nice Sorong local, but being from the blue line and linage proving to that makes it a small gold mine.
A true blue snake is one who completes it's ontogenic color change into blue. Hormonal blue has been discussed, but to me it's irrelevant. If it is genetic, it only appears in females who have breed. If she turns blue,and stays blue, after her first clutch and breeds the next season, it will not make your chances of getting blue babies any more likely. However, it does make for a nicer animal to look at.

If I have been keeping up with everything correctly (and at the breeding part, it's more in Brandon's court) Blue line is either from a descendant of Mr. Blue or Carolina Blue. A super blue line is when you breed a descendant of each together. There are defiantly many other blue lines out there, but these are the main two. Kirk Mills has a snake called "Arctic Blue" which from my understanding is a WC import from Indonesia. He got 2 clutches from him this year, but I don't think any he has had in the past have put out their adult colors yet.
