Abstract

The DNA fingerprint polymorphism and the genetic relationship were studied by RAPD technology on Chaidamu goat (CG), Chaidamu Cashmere goat (CCG) and Liaoning Cashmere goat (LCG) from Chaidamu Basin of Qinghai province, China. The results showed that: The amplified bands were all 94 in 3 goat populations by using 8 random primers, and the DNA polymorphism frequencies of CG, CCG and LCG were 0.8404, 0.8617 and 0.8511, respectively, and the length of these DNA fragments were 176-2937 bp. The mean heterozygosities of the 3 goat populations were 0.5148, 0.5142 and 0.5075, respectively. The genetic relationship between CCG and CG or LCG were similar (Gst=4.37% and 3.79%; $D_{ij}=0.0109$ and 0.0106), and that between CG and LCG was further (Gst=13.14%; $D_{ij}=0.0230$). These results also showed that the genetic relationship between CCG and LCG was the closest, then CG and LCG, and CG and CCG was distant.
