[Genetic polymorphism of the amylases found in species of Artiodactyla by means of polyacrylamide gel electrophoresis].

Three different types of isoenzymes, Am1, Am2 and Am3 have been revealed by polyacrylamide gel electrophoresis (PAG) and affine PAG electrophoresis in artiodactyla. In cattle and pigs Am2 isoenzyme is monomorphic, as shown by PAG electrophoresis, and polymorphic in affine gel separation (two alloenzymes, Am2A and Am2B have been revealed). Some of sheep have no Am2 isoenzyme, which, apparently, account for the presence of minus-allele. Am2 isoenzyme was not detected in Saiga tatarica which are related to sheep. In reindeer, Am2 system is monomorphic, Am3 system is polymorphic, in reindeers, Saiga tatarica and pigs the variability of the latter system being determined by A3A, A3B alleles.
