“…The Noire de Thibar breed displayed the highest proportion of loci with rare alleles and the highest proportion of loci, out of the total SNP set, showing heterozygote excess. These results are consistent to previous genetic diversity studies of Tunisian sheep populations using nuclear microsatellites (Kdidi et al, 2015a) and Y chromosome markers (Kdidi et al, 2015b).…”

“…However, the frequency of most common Y chromosome haplotype(s) found in different countries were as follows: 72.8% H6 [29] in African breeds; 60.7% H6 [7,8] in sheep breeds from all over the world; 65.0% [30] in Northern Eurasian breeds; 55.5% H8 and 34.5% H6 [31] in Tunisian breeds; 43.4% H6 [32] in Chinese breeds. Thus, it seems that H6 haplotype is the most frequent haplotype (except in Tunisia) in most of the places of the old continents.…”

In this study, 182 male animals from 12 native sheep breeds, as well as Karacabey Merino and Karagül breeds of Anatolia, wild sheep Anatolian Mouflon (Ovis gmelinii anatolica) were used as the study material. Based on SRY and SRYM18 regions on the Y-chromosome, haplotypes of the populations were analyzed using DNA sequence analyses. The SRY region, A-oY1 allele was observed in all of the individuals studied. On the other hand, four different alleles corresponding to four Y-chromosome haplotypes were detected at the SRYM18 microsatellite region. Among native Anatolian breeds (n=143), H6 haplotype (80.41%), H4 haplotype (9.09%), H8 haplotype (8.40%) and H12 haplotype (2.1%) were identified. H6 haplotype was observed in all 16 individuals of Ovis gmelinii anatolica. Pairwise FST values based on haplotype frequencies were calculated for domestic sheep, and the highest FST value was observed between Karagül and Kıvırcık along with Karagül and Ovis gmelinii anatolica with pairwise FST value of 0.43202 (P<0.01). Y chromosome polymorphism of sheep from Turkey were examined comparatively with the accumulated data in the literature. Out of seven haplotypes (H4, H5, H6, H7, H8, H12, H19) observed in Europe and Asia, 4 haplotypes (H4, H6, H8 and H12) were observed in Anatolia. H12 was a private haplotype of Sakız, H6 seems to be the predominant haplotype of domestic sheep (79.51%) as well as being the only haplotype observed in Ovis gmelini anatolica. H4 haplotype seemed to be associated with fat tailed sheep migrating to Turkey, entering from south east of Turkey, which may be related with the arrival of nomadic Turks.

Y kromozomunda bulunan SRY 5'promotor bölgesi ve Y kromozomuna özel bir mikrosatellit olan SRYM18 bölgeleri DNA dizi analizi yöntemleriyle incelenmiştir. SRY bölgesine ait analizlerde tüm bireylerde SNP A-oY1 alleline rastlanmıştır. SRYM18 mikrosatellit bölgesinde ise 4 farklı allel görülmüş ve toplamda 4 farklı babasal soy, haplotip, tespit edilmiştir. Yerli Anadolu ırklarında (n=143), H6 haplotipi (%80.41), H4 haplotipi (%9.09), H8 haplotipi (%8.40) ve H12 haplotipi (%2.1) belirlenmiştir. Ovis gmelinii anatolica'nın 16 bireyinde de sadece H6 haplotipi gözlenmiştir. Evcil koyunlar için haplotip frekanslarına dayalı FST değerleri hesaplanmış ve en yüksek FST değeri Karagül-Kıvırcık ve Karagül-Ovis gmelinii anatolica arasında FST değeri 0.43202 (P<0.01) gözlenmiştir. Türkiye koyunlarının Y kromozomu polimorfizmi literatürdeki birikmiş verilerle karşılaştırmalı olarak incelenmiştir. Avrupa ve Asya'da gözlenen yedi haplot...
