genome-wide analysis of italian sheep diversity reveals a strong geographic pattern and cryptic relationships between breeds.italy counts several sheep breeds, arisen over centuries as a consequence of ancient and recent genetic and demographic events. to finely reconstruct genetic structure and relationships between italian sheep, 496 subjects from 19 breeds were typed at 50k single nucleotide polymorphism loci. a subset of foreign breeds from the sheep hapmap dataset was also included in the analyses. genetic distances (as visualized either in a network or in a multidimensional scaling analysis of identical by state ...201424303943
