• The PigBioDiv2 project will evaluate and compare genetic diversity among the pig breeds of China and Europe. At least 50 Chinese breeds will be sampled and compared with 59 European breeds previously sampled in the PigBioDiv1 project. The European pig biodiversity database will be extended to at least 100 breeds, one third of the world's total number of pig breeds. Relationships among breeds will be determined by estimating genetic distance based on microsatellite markers and haplotypic relationships from mtDNA and Y-chromosome polymorphisms. The project will also determine the relationship between general measures of genetic diversity, such as genetic distance, and functional differences among breeds by characterising trait gene loci (type I markers) and QTL regions. Measures of diversity derived from anonymous markers (microsatellites) will be compared to measures derived from the trait genes. New approaches using DNA marker (genetic) data to identify genes involved in functional differences between breeds will also be developed.
