I think it shoots down to line breeding for polygenetic traits, much like dog breeders breed dogs or crested gecko breeders breed crested gecko morphs. It can't be narrowed down to punnet squares like ball pythons, but instead, you use caveman logic and put blue with blue and hope you get blue.
Although, word on the street is that there is an albino GTP or two floating around out there.

Um, it's actually even simpler than this. It's line breeding . . . just selectin brighter and brighter individuals, to keep them reproducing. Some individuals will look even brighter when they are adults, some will look much worse as adults. It's not a controlable factor.
The other thing that plays a VERY important role in GTP breeding outcomes is the locale - just like with reticulated pythons where knowing the locale of an animal is quite important to understanding its size range, and other factors, understanding GTP locale information will give you an idea of what the offspring will look like as an adult. Few people try for pure lines of GTP, most or two - three locale crossings to try and enhance the yellows or blues, Biak x Aru is a REALLY common one in this example.
Keep in mind, a polygenic trait is something like the Tiger gene in morelia, it IS heritable to a point, it will either be a weak influence, no influence, or strong influence, but with line breeding, if you cross an ugly parent to a nice parent you are likely to not produce any ones that resemble the nice parent, but more than likely a mix.

makes total sense now! how long can line breeding generally be practiced before you face problems/ defects?

Re: explain gtp genetics to a ball python person
Can we all just have a moment of silence in thanks to ball pythons for having such straightforward genetics?

You may think that I have not "Thanked" you for this post. However, I have actually "Thanked" you silently. Trust me.

I've heard 3 generation crosses back to parental lines is fine - but it's really more complex than that. Line Breeding causes something that is referred to as "genetic depression" when your stock genes end up kind of the same. . . . this is why genetic outcrossing becomes so important - which is possible when you are working with dominant / co-doms.
The thing is, when you work with the same line over and over again you start to see that the flaws of that line get enhanced. Then you also get to see the unfortunate things like lethal recessive genes become expressed. Many organisms are het for lethal combos, when you line breed (inbreed) you run the risk of hitting these combos with the young, and then leading in retarded, deformed, or lethal during development offspring.
On the opposite end of the spectrum. This is more common in more advance genomes like that of humans and higher structured animals. So in theory its safe to linebreed reptiles fairly deep before you witness the negative effects. But to put it in perspective I'll quote a famous genetics author - "You wouldn't be here if it weren't for a little (or a lot) of inbreeding"

Don't you be trying to get a peek at my rack! I know, I know, it's very nice, not every day do you see such a lovely 10 high 41 qt. I helped built it myself!

I already got to see a nice little peek on FB!
Was hoping to get the full view!!
And you did a :cens0r: fine job building that rack I must say!
