Study of mitochondrial DNA (mtDNA) D - loop region polymorphism in Şavak Akkaraman sheep

Abstract

This study was conducted to investigate the maternal genetic diversity using the mtDNA D - loop region 842 base pair (bp)polymorphism in Şavak Akkaraman sheep raised in the province of Erzincan. According to the results, in the mtDNA D - loop of theŞavak Akkaraman breed, 27 polymorphic sites and 20 haplotypes were identified and then, 11 of the 20 haplotypes identified in Şavaksheep were in haplogroup B (55%), 6 in haplogroup A (30%), and 3 in haplogroup C (15%). Haplogroup B was the most frequenthaplogroup in Şavak Akkaraman sheep. Haplotype and nucleotide diversities were estimated to be 0.995 ± 0.004 and 0.0146 ± 0.0003,respectively. The Şavak Akkaraman breed was compared with the mtDNA sequencing of different breeds and wild sheep, and thecontribution of the breed to biodiversity was considered.
