[QUOTE="Ebenezer, post: 1756661, member: 24565"] Not a big deal: semantics maybe, but I disagree. Within species and breeds, the pressures, selections and culling can remove genes over time. This is more important in minor breeds as a closed herd or flock over time creates a unique genepool which can actually create a hybrid pop when reintroduced into the mainstream of the breed or other pocketed populations. A geneticist told me that in long term closed populations there are alleles that do not remain due to others being dominant or by random loss. That is true evolution. Just as the whole of breeders fear and dis inbreeding, there are sterling examples in studied populations which are totally isolated yet thriving and from a narrow (bottle necked) origin without issues. Red Deer, Soay Sheep... But surely do not study the science. Just repeat without the mind in gear: " If it works it is linebreeding but if it doesn't work it is inbreeding" and "Never inbreed or you'll create defects"! Funny thing on the Soay sheep study: they are seeing quite a variation in color and patterns. But that's for another day. [/QUOTE]
