I would say grandfather-granddaughter us acceptible if there's nk prior inbreeding. This would require to breeding pair to start, cross the second generations with each other, then breed the third generation with the first.
Sigh......all the boys died from the second generation due to predators last fall.
I suppose if i wanted to do a proper line breeding Jake would have to go back to Faradays and visit Poof Poof. Lol.
