Line breeding will be breeding of distant relatives...cousins, uncles/aunts, etc.

What happened was an accident, I'm sure, but an accident that shouldn't have happened. Anyway, hope that this helps.

*edited to add* there is a chance for problems since the genes are closely related. That's why only seasoned breeders should even attempt an inbreeding.
