The Nov. 2009 Sus scrofa draft assembly (SGSC Sscrofa9.2 (NCBI project 10718, GCA_000003025.2)) was produced by the Swine Genome Sequencing Project and the Wellcome Trust Sanger Institute. For more information about this assembly, see Sscrofa9.2 in the NCBI Assembly database.
A genome position can be specified by the accession number of a sequenced genomic region, an mRNA or EST, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the Pig genome. See the User's Guide for more information.

The pig genome assembly is a hybrid of BAC end-sequencing to anchor contigs combined with whole-genome shotgun (WGS) libraries. See also: Porcine Genome Sequencing Project description.
There are 19 chromosomes, chr1 - chr18, chrX plus the mitochondrial sequence chrM from genbank accession NC_012095 for a total sequence length of 2,262,501,571 bases. There are 31,203,023 'N' bases in gaps, leaving 2,231,298,548 ACGT bases.
Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or the Downloads page. The Pig browser annotation tracks were generated by UCSC and collaborators worldwide. See the Credits page for a detailed list of the organizations and individuals who contributed to the success of this release.
