I know that I have voiced this opinion before, but I am a champion of repetition.
I would like to suggest the following hypothetical. Supposing one person had a clutch of unicolor hatchlings that had 12 good eggs out of 12. A second person had an unrelated clutch that had 3 good eggs out of 6. How many of you would want a pair comprised of one animal from each clutch?
I sure wouldn't. I would be a lot happier with a pair of siblings from the first clutch.
It isn't all that important that sibling pairs are unrelated. The overriding factor is that the first clutch came from a mother and a father that were both highly fertile, which cannot be said for the second clutch. This is captive breeding we are doing, and these animals are not going to be reintroduced to the wild. For us captive breeders, fertility is the number one important issue.
I am not saying that preserving genes is without merit. But preserving bad genes is just stupid. If an inbred line is twice as fertile as a genetically diverse line, then we should spend more of our time perpetuating the inbred line. Maybe then, we can cross one breeder's inbred line with another's.
Anyways, I know that this hypothetical circumstance may not apply with Dean's and Steve's clutches. Also, we should try to have the best of both worlds, high fertility and genetic diversity.
Nonetheless, for a captive breeder, high fertility is a characteristic that should always outweigh genetic diversity.
