| The Karayaka is the most populous sheep breed in the Black Sea region of Turkey. In the present study, we investigated the intra- and inter-population genetic relationships among indigenous Karayaka sheep subpopulations. Nine microsatellites were genotyped for 64 individuals from Samsun, Ordu, Giresun and Tokat provinces. The average number of alleles ( span classCombining double low line inline-formula i N i a span ), allelic richness ( span classCombining double low line inline-formula i A i r span ), observed heterozygosity ( span classCombining double low line inline-formula i H i o span ), expected heterozygosity ( span classCombining double low line inline-formula i H i e span ), polymorphism information content (PIC) and inbreeding coefficient ( span classCombining double low line inline-formula i F i IS span ) for all subpopulations were estimated as span classCombining double low line inline-formula i N i aCombining double low line16.44 span , span classCombining double low line inline-formula i A i rCombining double low line9.887 span , span classCombining double low line inline-formula i H oCombining double low line0.303 span , span classCombining double low line inline-formula i H i eCombining double low line0.886 span , span classCombining double low line inline-formula PICCombining double low line0.866 span and span classCombining double low line inline-formula i F i ISCombining double low line0.630 span , respectively. The observed and expected heterozygosity ranged from 0.171 (Giresun) to 0.376 (Ordu) and 0.757 (Samsun) to 0.845 (Ordu), respectively. It was determined that a 10.5 of total genetic variation ( span classCombining double low line inline-formula i F i ITCombining double low line66.9 span ) in Karayaka sheep corresponded to genetic differences among subpopulations ( span classCombining double low line inline-formula i F i ST span ), whereas 63.0 was explained by genetic difference among individuals ( span classCombining double low line inline-formula i F i IS span ). This study gives the first evidence about genetic relationships of Karayaka subpopulations. The results show that Karayaka sheep subpopulations are genetically different from each other. These findings revealed that the Karayaka breed has discrete subpopulations and should be taken into consideration when preparing conservation programs and future breeding strategies. p . |
