The performances of 17 isozymesin 8 kinds of tissues or organs were screened preliminarily in a TC-7.0 buffer system. The resultsshowed that the screened isozymes displayed remarkable tissue-specificities. Finally, 14 enzymes(AAT, ADH, EST, OPI, G3PDH, IDHP, LAP, LDH, MDH, MPI, PGDH, PGM, SDH and SOD) and 4 kinds of tissues(eye, skeleton muscle, liver and heart) were selected for genetic analysis. Fourteen isozymes areencoded by 20 loci, and 9 of them are polymorphic. The polymorphic loci are AAT-1~*, GPI-2~*,G3PDH~*, IDHP-1~*, LDH~*, MPI~*, PGM-1~*. PGM-2~* and SDH~*, and the proportion of polymorphic lociis 0.4500 (P_(0.99)) ? The mean values of observed and expected heterozygosities are 0.0278and 0.0265, respectively and the average effective number of alleles is 1.0675.展开更多
