GENETIC DIVERSITY OF ARABIAN HORSES USING MICROSATELLITE ‎MARKERS

SUMMARY The horse strains designation system was shaped in the 7th century in the Arabian Peninsula and spread to the neighboring oriental empires and it is still used. The aim of the present study was to investigate genetic diversity among three Arabian horse strains using twelve equine microsatellite markers. The study included 84 Arabian horses representing three major Syrian strains (Hamdani, Kahlawi and Saglawi) from five geographical regions in Syria. To determine genetic population structure within and between the three strains, we applied different methods. The selected panel of microsatellite markers confirmed a general genetic feature of the three main strains of Syrian Arabian horses suggesting low level of population differentiation. To ascertain the results, it will be necessary to collate our findings with the historical pedigree. Furthermore, we need a genome-wide investigation of microsatellites or an analysis of strain/breed specific SNPs across the Syrian Arabian horse populations for better insight into the genetic diversity.
