Would love for someone to do this with Bone:
A significant advantage of linebreeding over ordinary inbreeding is that, while it also increases homozygosity and prepotency, "the homozygosis produced by linebreeding is more apt to be for desired traits than is the case with undirected inbreeding. Linebreeding tends to separate the breed into distinct families, each closely related to some admired ancestor, between which effective selection can be practiced."
Don't miss the significance of this last point. Lush is saying that if there are multiple lines of animals linebred to a common ancestor, the breeder can manage inbreeding by using those groups as a source of animals for outcrossing while still maintaining the strong genetic influence of the ancestor. And because these groups of animals have not been interbreeding, they can be used to produce offspring that will have a lower rather higher inbreeding coefficient, and thus will benefit from hybrid vigor (a reduction in inbreeding depression) as well as a diminished risk of genetic disorders caused by recessive mutations.
He has bred enough females that this would work on him
