Sažetak
Montenegro has a high diversity of autochthonous and locally developed sheep breeds, adoppted to different regions and climatic zones. However, present trend of constant declining of sheep number lead some of them in danger of extinction. Our aim was to investigate the genetic diversity and population structure of five Montenegrin sheep populations, using OvineSNP50 BeadChip. To evaluate admixture contributions and genetic relations from sheep population in Montenegro, a set of worldwide breeds from publicly available genotypes was added to our data. Higher genetic diversity and low inbreeding was observed in Pivska Pramenka and Sjenicka Sheep, Ho = 0.411, He = 0.423, and FROH = 0.056 and Ho = 0.421, He = 0.421, and FROH = 0.041, respectively. While Zetska Zuja has a much lower FIS value (-0.002 to 0.0047) and relatively high FROH inbreeding (0.090), which indicate small population size and genetic drift. Also, long ROH segments (ROH > 8 Mb) were predominant in all populations. Population genetic structure analyses showed that the Montenegrin sheep populations are genetically distinct populations. This analysis previously revealed the presence of admixture in most sheep population (high heterogeneity), while genetic purity was observed in Zetska Zuja. The obtained results will help in the conservation management of Montenegrin sheep populations, especially for endangered breeds.
