Bloodline means a particular line of boas.
Salmons are a bloodline of hypo.
Davey Pastels are Davey's bloodline of pastel.
EBV Red Groups are east bay vivariums bloodline of pastel.
etc..
"I say that unless red is continually added by selective breeding, it will dissapear."
No. Failing to selectively breed towards red will not make an anery (no etherin).
The only way to highly reduce etherin is to selectively breed it out. In every litter you will have a variation of levels of etherin in the boas. In order to decrease etherin you would have to breed the individuals with the least amount of red over many generations. Etherin is often covered up by melanin. Many boas with high etherin will not show it because they have too much melanin, which covers it. In order to reduce etherin, melanin would need to be reduced and again, the red would need to be selectively bred out. Adding etherin (red) works the same way as eliminating it. Whether or not you could completely eliminate etherin (ie make an anery boa) through selective breeding is up for debate, I would doubt it. Its likely that could only happen through a mutation.
"I realize what the rule book already states, but I sumwhat dissagree. If Pastels are produced by stringing a known characteristic in a boa to accelerate and accentuate that known trait then it will reverse when the stringing stops."
If the pastel phenotype is defined in any way by color, how much color does there need to be for it to be described as a pastel?
The originator says none... it has no bearing in DEFINING what is and isnt a pastel. Pastel only describes a reduction in black.
The goal of pastel is to breed towards more color (red or yellow) and pastel bloodlines will have color tied to them.
Anyone who says color defines a pastel does not understand the trait or is thinking of a pastel bloodline rather than the phenotype defenition "Pastel". This often causes confusion.
"Black is dominant."
I dont even know how to answer that one. If you want to explain what you mean by that further I'll be glad to help you understand. Melanin (Browns/Blacks) is controlled by multiple genes.
