I personally only did it (in SA) to produce new morphs and I keep accurate records. I was fortunate enough to also have over 50 unrelated leo's to breed from as well. Unfortunately inbreeding/linebreeding here is NZ is impossible to avoid. As has been stated, not enough record keeping has been done to establish which are or are not related. It is my understanding that all leo's in NZ are related due to the lack of importation. I am I right? Please correct me if I am wrong.
