In Breeding

[gregmonsta]

some inbreeding is required to bring out the various morphs... good idea not to go past f3....

Definitely, to prove out a morph it is an important tool when limited sources of the required genetics abound. Had my earlier attempts at my anery concinnus project worked out I would be in F3 territory by now. Luckily I have Richard's experiences to draw on now and I won't have to go beyond F2 to test my ideas.
Again, it's then down to the breeder to advertise and sell responsibly, as required.

Just another thought...
How many people realise that if a breeder has a pair that they bred last year, and again this year, a female from last year mating with a male from this year is genetically the same as mating siblings together? They don't have to be from the same litter.

Now an example of a different species...
I know that my Cuitzeos are an F1 and F2, and come from a breeder in Europe. I also know that every Cuitzeo in Europe will have come from a single source (albeit one that has multiple wild caught snakes and breeds to produce genetic diversity). If in 20 years time someone decides that they need to get new blood in, and looks to the US to bring in some new blood, there's a good chance that the snakes from the US would originate from the same European breeder because some of his snakes have found there way to the US.
I guess the point of this is, that over time the early records that would definitively show the bloodlines are likely to be lost, and it's in the fourth, fifth, sixth generation that the records would become most important. What we do today can and will impact on the hobby for decades.

Some great points there. You would hope that some fresh blood would still be brought in somewhere along the line, in reference to the snakes crossing the pond.
It's also worth considering that in the wild a certain degree of inbreeding will be quite common. We're talking cousins and extensions of such. Nature seems to want to allow some separation of siblings considering that males becoming fertile at a younger age. Somewhere down the line it will happen though, and not just in isolated populations.
Again, it's down to how you build your collection, to follow your model.

My parietalis group is unrelated despite 3 of my animals coming from the same, trusted breeder. The first male can probably be traced to WC and the others can probably also be traced further.
My radix group has the same ratio. Two Dutch breeders and completely different lines (can probably be traced further).
My concinnus are currently a pair of Belgian brothers (can be traced back to WC through 2 generations) and an unrelated German female (F1 of fresh WC). If I find another female, with the males being related, I would still consider all offspring as F1.
My infernalis can be traced back through point of sale to a bloodline in Berlin, I think (will have to read the scribbles again and double check, these may be F1). I can only potentially generate F1/2 here as it stands.
My marcianus are 'unrelated' and were deliberately bought from different sources by the previous owner.
My 'Florida blue' sirtalis group is two sisters and an unrelated male, again according to previous owner. Again, all offspring of these would be F1.
The others I do not plan to breed so I will omit these - Panama may come into it, but it's not planned for and she's WC.
