Double recessive projects?

[Pythonfriend]

inbreeding is debated so often, i just wont go there.

but there is a plan to get it done without inbreeding. it just requires a larger collection and you need to be in both recessive projects as well.

(just picking albino pied as a random example)

if you, for example, have enough pieds that you can find some that are unrelated and also some albinos that are unrelated, you can set up two different breeding groups to produce a bunch of double hets. then you pair all the double hets originating from one breeding group to double hets originating from the other breeding group. Now you can hit your double recessives completely without inbreeding.

But normally you just do the inbreeding until you hit your first visual double recessive albino pied. now you can breed that one to unrelated albinos and unrelated pieds to make albino het pieds and pied het albinos, or you can buy unrelated double hets from a different breeder to breed to your visual, either way, you have ways to reduce inbreeding after you got your first visual double recessives.

and generally the consensus is that one or two generations of inbreeding dont really harm BPs; the debate is how bad it gets if inbreeding just goes on and on. once you have the visual, outbreeding for fresh genetics gets easier. Most big, reputable breeders regularly do outbreeding to keep the genetics strong, also things get much easier if you have a large collection. if a really big breeder has lets say 30 albinos and 30 pieds and 15 albino pieds, and is every season producing some new hets and double hets (some with new extra genes), it becomes really easy to avoid inbreeding.
