Özet

Awassi is a versatile sheep breed, selectively bred for meat, milk, and wool production, and exhibits remarkable adaptability to challenging environmental conditions. It is extensively raised across southern Türkiye, Iraq, Saudi Arabia, Palestine, Jordan, and Syria. However, factors such as prolonged droughts, diseases, climate fluctuations, intense selection, and crossbreeding have collectively led to a substantial reduction in the genetic diversity and biological richness of the Awassi sheep population in the Fertile Crescent region. As a result, it becomes crucial to identify these breeds, ascertain their phylogenetic relationships, and institute protective measures. Preserving the genetic heritage of Awassi sheep holds paramount significance given its historical and ecological importance.

In this Study, the mtDNA D-loop region of Awassi sheep reared in Türkiye, was sequenced, information about domestication processes and haplogroups were obtained and phylogenetic analyses were performed by revealing genetic similarities/differences. For this purpose, a total of 75 sheep were sampled, the control region (D-loop region) of mtDNA was amplified by PCR and then sequenced. In this study, the median-joining network analyses conducted on Awassi sheep raised in Türkiye resulted in the majority of the studied samples being grouped together with HPG-C, E.
