The amplification results were then examined by PCRRFLP, and followed by DNA sequencing. The results: there is a polymorphism in the form of single nucleotide polymorphism (SNP) in the SH group in the field, there is a difference between the FSHR promoter gene sequence that contains polymorphism in the SH group and the gene sequence in the normal group and there is no effect of polymorphism in the FSHR promoter gene on silent cases. heat in FH cows.} }
