Following domestication, livestock breeds have experienced intense selection pressures for the development of desirable traits. This has resulted in a large diversity that display variation many phenotypic traits, such as coat colour, muscle composition, early maturity, growth rate, body size, reproduction, and behaviour. To better understand relationship between genomic composition arising from breed development, genomes 13 traditional commercial European pig were scanned signatures diversifying using Porcine60K SNP chip, applying between-population (differentiation) approach. Signatures found regions associated with traits related to standard criteria, colour ear morphology. Amino acid differences EDNRB gene appear be one these signatures, KITLG may another. Other signals including QTLs genes production growth, fat deposition. Some showing evidence introgression Asian breeds. When compared wild boar, high levels differentiation harboured bone formation,
