摘要
[ Objective] To study the polymorphism of follicle-stimulating hormone receptor （FSHR） gene in Ningxia Tan sheep and thus to provide a theoretical basis for breeding. I Methodl Genotypes of 111 healthy Ningxia Tan sheep were examined by polymerase chain reaction and restriction fragment length polymorphism （PCR-RFLP）. [ResultS] A 306-bp fragment was amplified. The PCR products digested with restriction enzyme Alu I showed polymorphism with three genotypes, L e., GG, CG and CC. The genotypic frequencies of GG, CG and CC were 0.135 1 （ 15 individuals）, 0.666 7 （74 individuals） and 0.198 2 （22 individuals）, respectively. The allele frequencies of G and C were 0.468 5 and 0.531 5, respectively.[ Conclusion] FSHR aene is Dolvmomhic in Ninaxia Tan Sheeo.
