Table 2.

Pairwise genetic distances (FST) between Thoroughbred, Arab, Oriental and British Native horses. (Negative values result from the inaccuracy of the Arlequin v. 3.11 algorithm's estimates when FST values are near zero, especially when combined with the small sample sizes of the Anatolian, Caspian, Connemara and Shire breeds.)
