“…Kuzsca et al (2008) found notably higher FIS values in the Kıvırcık sheep populations from Thrace and Marmara (0.374 and 0.282, respectively) than the FIS value found in the present study ( Table 2). The FIS values found for the Slovak and Hungarian Tsigai sheep breeds were also higher than those of the present study (0.252 and 0226, respectively) (Kusza et al, 2009(Kusza et al, , 2010. In contrast, the FIS values found in our study are quite high compared to the FIS values found in the Merino populations from different countries (Diez-Tascόn et al, 2000), Muzzafarnagri (Arora and Bhatia, 2004), Manchega and Churra (Calvo et al 2006(Calvo et al , 2011, Romanian Tsigai (Zăhan et al, 2011).…”

In this study, animals from the Kıvırcık breed of sheep and two closely related breeds (Pırlak and Karacabey Merino) were analysed by using 15 microsatellite markers to evaluate the genetic diversity within the Kıvırcık breed and to elucidate its relationship with the other two breeds. A total of 244 alleles were detected on all of the 15 microsatellite loci studied. While the Kıvırcık population of sheep showed a significant deviation from the HardyWeinberg equilibrium (HWE) for all 15 loci, both the Pırlak and Karacabey Merino breeds showed a significant deviation from the HWE for 10 loci. The mean observed heterozygosity and FIS exhibited ranges of 0.63 to 0.72 and 0.0672 to 0.2139, respectively. The highest mean number of alleles value and the greatest number of private alleles were observed in the Kıvırcık population. While microsatellite analysis revealed high genetic diversity in breeds investigated, a high level of inbreeding was also observed between different Kıvırcık populations and other two breeds. The genetic differentiation between breeds was found to be low. The Kıvırcık from Istanbul and Bursa were the most closely related genetically, while the Kıvırcık from Manisa differed from the other populations. In addition, the Karacabey Merino and Pırlak breeds grouped together.

Our results are similar to those reported by (Nanekarani et al, 2010) for pelt sheep breeds of Iran (0.018).…”

Regardless of the approach used, most of the studies carried out are limited to a single country (Álvarez et al, 2004;Glowatzki-Mullis et al, 2009), while historical relationships among neighbouring sheep populations suggest the need of crossborder analyses (Tapio et al, 2005(Tapio et al, , 2010Cinkulov et al, 2008;Kusza et al, 2008;Salamon et al, 2014).…”

The knowledge of the genetic composition and relationships among livestock breeds is a necessary step for the implementation of management and conservation plans. This study aims to characterise the genetic diversity and relationships among six sheep breeds of meat aptitude that are spread through the eastern Pyrenees: Tarasconnaise, Castillonnaise and Rouge du Roussillon from France, and Aranesa, Xisqueta and Ripollesa from Spain. All but Tarasconnaise are catalogued as endangered. These breeds do not share the same ancestral origin but commercial trades and gene flow between herds are known to have occurred for centuries. Additionally, two outgroup breeds were included: the Guirra, from a different geographical location, and the Lacaune, a highly selected breed of dairy aptitude. A total of 410 individuals were typed using a panel of 12 microsatellite markers. Statistical, phylogenetic and Bayesian analyses showed that eastern Pyrenean breeds retained high levels of genetic diversity and low, but significant, levels of genetic differentiation (FST = 4.1%). While outgroups were clearly differentiated from other breeds, Pyrenean breeds tended to form two clusters. The first encompassed Tarasconnaise and Aranesa, which probably descend from a common meta-population. The second tended to group the other four breeds. However, none reached high mean Q-values of membership to a discrete cluster. This is consistent with the recent past gene flow between breeds, despite different ancestral genetic origins. The genetic characterisation carried out of the eastern Pyrenean sheep populations provides useful information to support decision making on their conservation and focusing efforts and resources to more singular breeds.
