Study: Arabian DNA Reveals Diversity, Other Breed Influences
On the contrary, the Arabian breed is, for the most part, “genetically healthy,” with significant diversity in its genes, both in its homeland regions of the Middle East as well as abroad, said study author Samantha A. Brooks, PhD, of the Department of Animal Science in the Genetics Institute of the University of Florida, in Gainesville.
Plus, some sire lines aren’t nearly as pure as their breeders might think, she said. Their genomes reveal significant interbreeding, primarily with the Thoroughbred.
Good News or Bad News?
The international team of 19 researchers involved in this study came to clear conclusions: In at least one line of Arabians—the flat racing lines—many individual horses have mixed blood bearing the influence of other breeds, mainly the Thoroughbred, said Brooks. Some horses had up to 62% of their DNA coming from the
