Genetic variability in the Skyros pony and its relationship with other Greek and foreign horse breeds
In Greece, seven native horse breeds have been identified so far. Among these, the Skyros pony is outstanding through having a distinct phenotype. In the present study, the aim was to assess genetic diversity in this breed, by using different types of genetic loci and available genealogical informat...
