 The Naturalean division is for Piedmontese cattle that are either crossbred or could have qualified for <unk> registration but failed to meet the pedigree requirements , perhaps because of unregistered or unverified parentage . Prior to registration or recording , DNA testing is required to confirm the animal carries at least 1 copy of the Piedmontese @-@ specific myostatin gene . Naturalean animals that are DNA tested heterozygous ( 1 @-@ copy ) are not registered , rather they are issued a registration number with the prefix " recorded " . The 0 @-@ copy ( non @-@ carriers ) cattle are ineligible for registration in any category .
