| Abstract: | The aim of experiment was to analyze the polymerization effect of genotypes and genotype combinations of PRLR and LH?? gene loci in Xinong Saanen goat by SSCP marker and family trees. The relationships of genotype combinations and litter size were compared in Xinong Saanen goat. The results indicate that there are genetic polymorphisms at the PRLR and LH?? gene loci, and there are 4 positive genotypes (GG, CC, PP and LL) and 4 negative genotypes (HH, DD, QQ and MM) effects on litter size, respectively in Xinong Saanen goat. Compared with the other genotype combinations, the polymerization effect of GGCCPPLL markedly improved (P?
