Variations in alleles,polymorphism information contents(PIC) and populations heterozygosity(H) in Juema pig were analysed by using 9 microsatellite DNA markers.148 alleles in total were found in 5 pig populations,while the average alleles number of Juema pig was 55,the average observed heterozygosity and expected heterozygosity were 0.836 6 and 0.861 5 respectively,the value of average PIC was 0.824 8.The results indicated that,by comparing Juema pig with Lanzhou,Lintao,Qinghai and Wuwei pig populations,its heterozygosity and polymorphism information contents were low,but in Juma pigs,with Ho0.7,HE0.8,PIC0.7,which might be possible that Juma pigs to be greatly effected by Sus scrofa,and there were more genes resource in Juema pig,with comparatively high heterozygote,large genetic variance,abundant heredity polymorphism and stronger ability to fit on arcticalpine environment.
