Protein electrophoresis was used to examine theblood protein polymorphism in Yunnan local pig breeds,i.e., the Saba pig, Dahe pig, and Diannan small-ear pigbreeds. Of 38 genetic loci surveyed, 9 were found to be polymorphic. The percentage ofpolymorphic loci (P) varies from 0.1875 to 0.2121, andthe mean individual heterozygosity (H) varies from0.0712 to 0.1027 in three pig breeds. The resultsindicate...
Restriction endonuclease cleavage patterns of mitochondrial DNA(mtDNA) of three local types of Yunnan native water buffalo were analyzed using 18 enzymes which recognize six nucleotides. Among the 12 animals analyzed, 3 of 18 enzymes, BamHI, EcoRI, and ScaI, revealed polymorphisms. Three mtDNA types were identified. The results indicate that a relatively low level of mtDNA variation exists in Yunnan domestic water buffaloes. The origin of Chinese buffalo derived from Yunnan province of China is discussed....
