- Abstract
SSCP were employed to investigate the genetic polymorphism of sheep GH gene and to analyze the correlation of genetic polymorphic sites with growth traits. The results showed that AA, AB and BB genotypes were detected in exon II of GH gene in the six sheep populations. The highest frequencies of AB genotype detected in Mongolia sheep, Small-tailed han sheep, Tong sheep, Lanzhou large-tailed sheep and Henan large-tailed Han sheep were 0.375, 0.531, 0.545, 0.350 and 0.596, respectively, and the highest frequency of BB genotype in Yuxi fatty-tailed sheep was 0.378. Exon II of GH gene was significantly correlated with body weight, carcass weight, chest width and hip height (P<0.05). Moreover body weight and carcass weight of AB genotype were significantly higher than those of AA and BB genotypes (P<0.05) and chest width and hip height of AB genotype were remarkably higher than those of AA genotype (P<0.05).
