Thanks for confirming RD. It was the only logical path I could see. You breed what you consider two good representatives of the traits you want. You grow that generation to a decent size and try and determine what are dominant, co-dominant and recessive traits. Whether you can or can't you at very least try and breed the best representatives of that generation to one another or other similarly aimed previous or current stock. Influx new blood as necessary to try and keep at bay any bad recessive genetics from making there way to the surface.1K sounds about right. These types of "super" specimens is I believe where the term SRT comes in to play.
And Kolt, your speculation is pretty much bang on. Most of the lower quality RT's that show up in the hobby are first generation RT's, and are often the result of a female BP, and a male "texas". Many of those juvies never result in anything, some peel and look so-so, and maybe 1 out of thousands ends up red, or reddish, and is actually worth the name RT. Most are orangish, even if they do peel they never become truly red.
Lots of the imported RT's also do not turn out to be rock stars once they mature. Too many pearls (like my fish), or they become orange, not red, or they never fully fade or peel, with too much black showing. It's for this reason that I used to always recommend that people buy an RT that has already peeled, and is showing most of its full potential - vs spending a bunch of money on a 2-3" fish that is too young for most hobbyist to properly grade. Many turn out to be duds - of course the breeder or overseas vendor knows this.
I don't know how many people remember CJbarth, but several years ago he was breeding RT's, using a female RT (imported) and a male carpintis I believe. He produced a LOT of juvies, a few turned out very nice, one particular male was really nice as he matured, but unfortunately he too stayed orange. But CJ only charged $10 per fish as I recall.
I'm not in anyway any good at genetics but from what I see it looks as though the pearls are a dominant trait and the coloration is co-dominant. Which is why from what I've seen the pearls always carry over suggesting a dominant trait, as does the color but to a lesser degree suggesting a perhaps co-dominant trait. Body shape I have no idea it might also be a co-dominant trait since it seems first generation tend to be different mixes between the two parents. Again I'm just speculating and I'm not even what I would consider a novice when it comes to genetics.
I've wanted to try a Red Texas project myself but I doubt I have the patience, money or skill to pull it off. Especially since who knows what's fertile and what's sterile in the market when it comes to Hybrids. I've heard some male BP's are but have yet t hear even a rumor about KKP's, SKKP's, RT's, SRT's and the various imitations out there. And as someone whose been shelling out money for higher quality hybrids lately it's an interesting coincidence or maybe not that what's available of high quality Hybrids available tend to be males. Perhaps like stingray and ball python breeders females are more likley to be held back by the owner. Another interesting thing I've noted is I see more Short Body RT's and SRT's that are of a high quality then their normal bodied counterparts.
I remember CJbarth. I always wanted to pick up some of his stock but they used to sell really fast. IMO his line would have been a great place to start for anyone trying to breed RT's and SRT's. Just shell out for a high quality RT or SRT and maybe a imitation Mammon or SKKP and Carpintis and cross the best of their fry back and forth. Probably would have had some decent specimens out of that in a couple of years.
