Studies of Random Amplified Polymorphic DNA(RAPD)of Different Goat Populations Crossbred by Boer Goat
波尔山羊杂交后代及其亲本随机扩增多态DNA研究

The random amplified polymorphic DNA（RAPD）of 128 individuals was studied,which were from Boer goat， Tangshan dairy goat,Qinglong native goat and their hybrids crossbred with Boer goat.The average index of genetic polymorphism for whole population（Hsp）and the index of genetic differentiation were 0.6974 and 0.9706,respectively.The average index of genetic distance between populations（0.1314～0.2052）was significantly higher than that within populations（0.0582～0.1440）.All of these indicated that the genetic polymorphism was not only abundant，but also the genetic variation was mainly existed between goat populations.The molecular dendrogram among goat populations was in accord with their genetic relationship.
