Famous, strong flying strains that can tolerate inbreeding, are always excellent strains for crossbreeding purposes!
The cardinal point in what Prof. Bonsma calls "erfdwang", I know to be prepotency. I've looked in vain through the various dictionaries to find a comparable definition. Prepotency is to be predestined, as it were, to have the potency to breed in an excellent fashion. Many say that prepotency "just happens" as a result of inbreeding. Prof. Bonsma believes it to be the winning number in a lottery. Breeding is, in a certain sense, a lottery. We never know exactly what is going to happen. He sees prepotency and heterozygote as not being necessarily opposites. I would like to quote him again. "Within every population group a few individuals play an immensely important role in the creation of the desired animals."
