Genotypes arising from the project are available from the EC Pig Diversity Database at http://www.databases.roslin.ac.uk/pigbiodiv. The database contains individual microsatellite genotypes and AFLP typings for pigs from 60 European breeds including lines derived from Large White, Landrace, Duroc, Pietrain and Hampshire. Pooled allele frequencies for 39 microsatellite markers in 96 European and Chinese breeds will also be available through the database, together with allele frequencies at 1315 single nucleotide polymorphisms (SNPs) (10 Chinese and 10 European breeds plus European wild boar), 30 of these SNPs were also typed across 25 European and 25 Chinese breeds, mtDNA polymorphisms (47 European and 19 Chinese breeds) and Y chromosome haplotypes (25 European and 25 Chinese breeds).
