In this study, the data set consisted of milk yield (MY) and milk content components; milk fat (MF), fat-free dry matter (FFDM),\rdry matter (DM), protein (Pro), lactose (Lac), pH, acidity H (aH), and lactic acid (Lac). Besides, Karakaş (n = 30) and Norduz (n = 26)\rsheep were chosen to investigate based on the SNP method. Correspondingly, genomic DNA from both breeds exon 2 of the GDF9 gene\rregion was amplified, 815 base pairs (bp) in length, by means of PCR. Therefore, there were three noval SNPs detected in both breeds\runder investigation. Although SNP1 and 2 with genotypes of GG and AG had statistically significant impacts on both milk production\rand milk components (p < 0.01), SNP3 with genotypes of TT, TC had no significant effects on the milk characteristics in question.eninfo:eu-repo/semantics/openAccessBiyolojiGenetik Ve KalıtımZiraat MühendisliğiVeterinerlikArticle455Q4Q3881889528183WOS:000711273500011
