Abstract
Sheep (Ovis aries) has played a major role in farming for food, textiles, and clothes since their domestication (ca. 11,000 years ago). Subjected to intense transportation, sheep have a complex demographic history. We examine
genetic diversity and historical demography of sheep breeds from Hungary and neighbouring areas. We analysed a total of 763 animals from 39 breeds, using genotyping data from the SMARTER database. Genetic diversity, population structure and individual genetic components analyses revealed a clear split in two subpopulations for the Hungarian Racka breed, maybe related to the different colour variants, and a low level of admixture for both Hungarian Racka and Tsigai. Several breeds showed introgression from Merino or Texel and gene flow between domestic breeds and their wild relatives. Historic trends in effective population size and runs of homozygosity revealed recent bottlenecks, confirming previous results and in agreement with documented demographic changes. Overall, our results provided clues on the possible events related to their early arrival in this area: the inferred admixture events, spanning from the Bronze Age to early Middle Ages, suggested bi-directional gene flow in several waves of contact.
