Identifikasi Keragaman Gen FSH Bagian Ekson 2 Menggunakan Enzim Restriksi TasI pada Sapi Pesisir

This study aims to identify the diversity of the exon 2 FSH gene using the restriction enzyme TasI in Coastal cattle. The blood samples used were 78 blood samples of two types, namely 13 males and 65 females aged 1-5 years, from coastal cattle obtained from BPTUHPT Padang Atas. The protocol genomic DNA Purification System Kit from Promega was used to isolate DNA from blood samples. The amplification of the FSH gene was carried out using the PCR or Polymerase Chain Reaction technique. The TasI enzyme was used to restrict the amplification product. The study results on the exon two portion of the FSH gene in coastal cattle showed two types of genotypes. The two types of genotypes are heterozygous (+/-) and untruncated homozygous (-/-); for males, 0.38 and 0.62, respectively, and the frequencies of allele (+) and allele (-) are 0.19 and 0. .81, while for females, it was 0.43 and 0.57, respectively, and the frequencies (+) and allele (-) were 0.21 and 0.79. The FSH|TasI exon two gene genotype distribution in the Coastal Cattle population is polymorphic (various) with an allele frequency of less than 0.99.
