>>BTW David...Hybrid Vigor applies to Hybrids which is in no way related to this discussion on inbreeding ..infact hybrid vigor couldn't be further from this topic.

Actually, Justin, that isn't really correct. In science, "hybrid" doesn't just mean the cross between two different taxa. In just means the cross between two unlike parents. Take two different inbred strains of research mice and breed them together. Although the parents are the same species, the offspring are a hybrid line becuase they come from two unlike strains. He is completely correct in saying that breeding two linebred strains of hognose could produce hybrid vigor. However, hybrid vigor is NOT always seen in offspring from unlike parents.

>>There are many documented diseases and disorders caused by repeatitive inbreeding..so it isn't a misconception. For example the Amish are well known for genetic disorders due to this.

Inbreeding increases the EXPRESSION of genetic disorders. It does not CREATE the mutation itself. I believe you missed the point of his post.
