PCR-RFLP results of different genotypes of the sheep FSHR genes. The genotypes are marked on the top of the lanes. A: PCR products digested by enzyme BsmI showed different genotypes of FSHR g.149A>G. B: PCR products digested by enzyme XmnI showed different genotypes of FSHR g.1235T>C. C: sequencing analysis of different genotypes of FSHR g.2357-2358 AG>CT.
