There is no shortage of pureblood specimens in the trade or in the wild. Ball pythons and blood pythons should be just fine even if a few hybrids make it into their gene pool. Do the majority of breeders have the same concern for Ball pythons with spiders & womas and their neurological issues, deserts with their female sterility, or inbreeding in general to develop/prove out morphs? I'm thinking both species will be ok.
