The pig represents a domesticated animal that has both a convenient number of outgroup species nicely spaced in evolutionary distance, as well as surviving wild conspecifics (see Figure 1). verrucosus, African warthog) that fall within a range of 1 to 6 million years ago (MYA) of inferred evolution [11-14] (Figure 1). Construction and evaluation of a porcine bacterial artificial chromosome library.
This renders the pig as perhaps one of the most suitable animal species for inferring ancestral mutations as well as determining the fate of derived states and selective processes. Darwin (1859) clearly believed both nature and artificial selection shaped breeds, “The key (to domestic breeding) is man's power to accumulative selection: nature gives successive variations; man adds them up in certain directions useful to him” .
Domestication also provides rapid phenotypic evolution through artificial selections. A somatic cell hybrid panel for pig regional gene mapping characterized by molecular cytogenetics.
Pig domestication has resulted in highly modified morphological architectures and has caused several major changes in physical types, e.g.
Pigs offer a unique opportunity to identify genes or genomic regions encoding quantitative trait loci (QTLs) since they have been through recent and strong selective sweeps targeted at phenotypes to improve agricultural performance and disease resistance.
The pig whole genome sequencing project has been launched in the early of 2006 initiated by the Swine Genome Sequencing Consortium (SGSC) ( It has been possible to discriminate more than 16 distinct subspecies, each occupying distinct geographical areas [5-8]. Domestication is the process of genetically adapting a wild biological organism to better suit the needs of human beings, as a result of living and breeding conditions under careful human control for multiple generations . Milan D, Beever J, Lahbib Y, Schook L, Beattie C, Yerle M. Swine genome sequencing consortium (SGSC): A strategic roadmap for sequencing the pig genome. This bottleneck affects all genes in the genome and modifies the distribution of the genetic variation among loci. Proceeding of the 30th international conference on animal genetics. The magnitude and variance of the reduction in genetic diversity across loci provide insights into the demographic history of domestication. Domestic pigs are found in a globally wide range of environments. Pigs in sequence space: A 0.66X coverage pig genome survey based on shotgun sequencing. Several features, including teeth and skull morphology, external proportions, hair and colour patterns, biochemical and molecular polymorphisms, ecology and behaviour, reproductive isolation and natural areas, are used for discriminating the many species in the genus Sus. scrofa is classed into a large number of subspecies, but the number is uncertain and depends on the definition of the subspecies. Keywords: Alternative splicing, Association mapping, Domestication, Genetic diversity, Genome sequencing, QTL, Selection, Selective sweeps, SNPs The recent completion of the human genome sequence provides a starting point for understanding genetic complexity and elucidating genetic variations contributing to diverse traits and diseases. Absence of correlation between DNA repair in ultraviolet irradiated mammalian cells and life span of the donor species. Pigs are even-toed ungulates belonging to the order artiodactyla, an order phylogenetically closer to primates than rodentia . scrofa, a wild boar, approximately 9,000 years ago in multiple regions of the world [2-4].
