| Summary: | The Pentro horse population is an autochthonous breed from a breeding area characterized by climatic and geographic<br />peculiarities. The horse population is interesting because of its rusticity, however, has run the risk of loosing its identity<br />because of the introduction of exotic genetic material. This study presents data of the genetic characterization by means<br />of microsatellite markers. A total of 12 microsatellite loci were used to score 147 individuals among those with the Pentro<br />phenotype, as well as 16 individuals representing the variable part of the population. Allele frequencies were calculated<br />for each locus, with the mean number of alleles (Nall = 6.7) and the expected heterozygosity (He = 0.724). The mean<br />observed heterozygosity was 0.695. The obtained data were used to compare the genetic structure of the Pentro horse<br />to six other Italian breeds. The N-J tree computed on individual genetic distances showed that 93% of Pentro horses clustered<br />together. |
