Short summary
Genetic variability and selection signatures were analyzed in Anatolian Merino  via 351.539 bi-allelic single nucleotide polymorphisms. Adequate genetic diversity with a low inbreeding coefficient was detected. Effective population size, however, showed a declining trend through generations. Selection signals were observed in 37 and 72 protein-coding genes via  two statistical approaches; a large part of them were associated with milk traits and udder morphology.
