Level of DNA Similarity the Horned and Polled Bali Cattle Using Microsatellite Approach

The phenomenon of polled on Bali cattle should have a scientific explanation that explains the validity of the breed. Whether Bali polled cattle still have a genetic relationship with Bali horns cattle or are the results of crosses with other cattle breeds remain unclear. This study used microsatellite markers to identify some of the genetic diversity and relationship between Bali polled and Bali horn in cattle. Samples of 40 polled and 189 horned Bali cattle aged 2.5-3.5 years old were used in this study. Research data analysis includes: genotype and allele frequencies, Hardy Weinberg Equilibrium analyze, observed and expected heterozygosity values, and polymorphic informative content. Results showed that Bali polled cattle have similarity genetic characteristics with Bali horn cattle based on HEL9, INRA035, ILSTS045, and HEL13 microsatellites. HEL9, INRA035, ILSTS045, and HEL13 microsatellite can be a genetic marker for Bali polled cattle.
