Re: Breeding brother/sister?
The nature of the genetics beast is....do it exclusively or too many times and you'll bring the undesirable traits to the forefront, but one or two generations should be okay...then outcross to an unrelated animal.
My het albinos and my het pieds are sibs b/c they came sold as pairs. But for my boas, my het albinos will be totally unrelated as the male is from Jimi here and the female is (hopefully) from a breeder in TX.
Like Adam said...some traits are more squirrely but once or twice...PERSONALLY, I'd not do it more than twice.
