	1	The Analysis for the Single Nucleotide Polymorphism of TGF-β1 and Its Association with Reproduction in Different Sheep Breeds显示文摘A single nucleotide polymorphism(SNP)of 805 bp region in the intron 6 of transforming growth factor β1(TGF-β1)gene was identified by polymerase chain reaction-single-strand composition polymorphism(PCR-SSCP)in 196 sheep among Small-tailed Han sheep,Tong sheep,Tan sheep and Oula sheep.Comparative sequence analysis of cloned products revealed an AGAC deletion at 294 bases upstream of exon 7 of the TGF-β1 gene(site 14201 in gi76871756).Statistical results of the genotype and allele frequencies in different breeds showed that genotype AB was dominant in the Small-tailed Han sheep.Genotype BB,however,was in majority in low-fecundity sheep.The results of a Chi-square test indicated that all the populations were in Hardy-Weinberg equilibrium.
