Overall, the Spanish Arab Horse can be described as a population without genetic subdivision and with a mating policy and historical constraints that reduced the available genetic variability regardless of the relatively large size of its founder population. Furthermore, 58 blood samples were obtained and genotyped from bay Asturcón individuals in order to place the results within the context of an unselected population with no known genealogies. Arab horses imported from foreign populations. analysed. genetic contribution as shown in Table 3. respectively. Herein, both genealogical and molecular methods are combined in order to assess founder representation, lineage, and allelic diversity. of parents (black series) calculated with POPREP [17].

Listed on “5 Most Endangered Horse Breeds,” the Cleveland Bay Horse is one of the oldest breeds from northeast England. Unfortunately, despite its history and qualities, the Cleveland Bay ’s numbers have dwindled to a mere 550 horses world-wide, with only 220 mares of breeding age. J Exp Biol. This was due to a breeding policy that included mating between relatives, but also due to the limited availability of reproductive individuals after the Spanish Civil War.
