Selection using genetic markers (MAS) is carried out in an effort to accelerate livestock breeding programs, through molecular studies individual superior livestock can be detected earlier so that the selection program can be directed and controlled. This study aims to analyze genetic diversity at the growth hormone locus that is thought to have a relationship with reproductive and production traits in Friesian Holstein Crossed (FHC) dairy cattle through the polymerase chain reaction - restriction fragment length polymorphisms (PCR-RFLP) method. The study was conducted in Pujon subdistrict using 53 FHC cattle samples. The results showed that at the GH gene locus only one genotype was found, AA with an allele frequency of 1.00. Based on these results, it was concluded that the GH gene in FHC cattle is monomorphic. The information in this study can be used as a reference in formulating livestock breeding programs.
Key words: Growth Hormone Polymorphism / monomorphic / Marker Assisted Selection (MAS)
