Clear evidence was obtained for domestication to have occurred independently from wild boar subspecies in Europe and Asia. PCR products were sequenced directly using the Big Dye terminator chemistry and an ABI377 Prism DNA sequencer (Perkin Elmer, Norwalk, CT). (A) Variable positions in the 5′ region of the mitochondrial DNA control region (440 bp) among wild boars and domestic pigs. Second, the molecular clock rate shows a considerable variation among lineages, possibly due to differences in efficiency in DNA repair, generation time, and/or metabolic rate (Li 1997). We observed five nucleotide substitutions in a segment of 784 bp (K = 6.4 ± 2.8 × 10−3 subs/site) between the GPIP*3 and *4 alleles, predominantly found in Chinese Meishan and European domestic pigs, respectively. The six positions involving amino acid substitutions are marked by asterisks. [1][2] The breed has a number of divisions, classified by some authors as strains[3] and by others as separate breeds. Pork fat is #8 on the BBC’s list of the world’s top 100 most nutritious foods. The aim of this investigation was to provide a more comprehensive molecular analysis of the origin of domestic pigs by analyzing wild and domestic pigs from both Asia and Europe. Loss-of-function mutations in this gene cause albinism in many species. The most likely explanation for the fairly high frequency of Asian mtDNA haplotypes in some European domestic breeds is that this is due to the documented introgression of Asian pigs during the 18th and early 19th centuries. The Taihu pig (Chinese: 太湖猪) is a domestic breed of pig from the narrow region of mild sub-tropical climate around the Lake Tai region in the lower Yangtze River Valley of China. An interesting finding was that the allele for black color in Asian Meishan and British Large Black pigs differed by as many as four nucleotide substitutions from the consensus of MC1R alleles in European domestic and wild pigs. 1995). It would be of particular interest to include wild boar populations with a karyotype of 2n = 36 in contrast to 2n = 38 in other wild boar populations as well as in all domestic pigs. The sequence divergence between the alleles at the three nuclear genes included in this study is also several times higher than that generally observed in humans (Chakravarti 1999). It should be noted that the confidence intervals for these two estimates are large and that they provide maximum estimates since part of the sequence divergence between the alleles may have occurred prior to the divergence of European and Asian populations. The hybrid origin of the Large White breed must also be taken into account when evaluating the results of pig gene mapping experiments involving crosses between this breed and European wild boars (Anderssonet al. The European clade 2 included only three wild boars from Southern Europe (Italy). This makes it easier for a breeder to select and stabilize the traits they want without having to undo several generations of bad breeding. Additional Information. The presence of distinct European and Asian mtDNA clades in domestic sheep has also been reported (Hiendlederet al. Rico Silvera of God’s Blessing Farm worked endlessly driving thousands of miles to obtain the last verifiable pure Meishans from all 3 facilities. First, there is a fairly large sampling error since we have studied only ~10% of the total mtDNA genome and a few nuclear genes. Generally, the Meishan Pig are heavy feeders and take large amounts of roughages. The data presented on the domestic pig add to an emerging picture of independent domestication of distinct populations of the wild ancestors of major domestic species. An obvious trait of the breed is their docility. Sequence identities and deletions are indicated by dots and dashes, respectively; missing data are indicated by blanks. Meishan Pigs are extremely docile and renowned for their tender and flavorful red meat pork. The first column indicates assignments of the haplotypes according to the SSCP analysis; dashes refer to the sequences available only in the nucleotide database that were not subjected to SSCP analysis (Table 1). for both the control region and cytB were obtained with maximum parsimony and maximum likelihood analysis (data not shown).
