In pigs genetic variability at the cytochrome B gene and the D-loop region has been used as a tool to dissect the genetic relationships between different breeds and populations. In this work we analysed four SNP at the cytochrome B gene to infer the Asian A1 and A2 haplotypes or European E1 and E2 haplotypes origins of several European standard and local pig breeds. We found a mixture of Asian and European haplotypes in the Canarian Black pig E1 A1 and A2 German Pietrain E1 A1 and A2 Belgian Pietrain E1 A1 Large White E1 and A1 and Landrace E1 and A1 breeds. In contrast the Iberian Guadyerbas Ervideira Caldeira Campanario Puebla and Torbiscal
