Canis familiaris "Tasha" (NHGRI Press Photos)

The July 2004 dog (Canis familiaris) whole genome shotgun (WGS) assembly v1.0 was sequenced and assembled by the Broad Institute of MIT/Harvard and Agencourt Bioscience.

### Sample Position Queries

A genome position can be specified by the accession number of a sequenced genomic clone, an mRNA or EST, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list provides examples of various types of position queries for the dog genome. See the User's Guide for more information.

Request: |  | Genome Browser Response:
chr16 |  | Displays all of chromosome 16
chr16:1-5000000 |  | Displays first 5 million bases of chr 16
chr16:1000000+2000 |  | Displays a region of chr 16 that spans 2000 bases, starting with position 1000000
AY572227 |  | Displays location of mRNA with GenBank accession AY572227
BM538765 |  | Displays location of EST with GenBank accession BM538765
chr6_8.29 |  | Displays location of Genscan gene prediction with identifier chr6_8.29
pseudogene mRNA |  | Lists transcribed pseudogenes but not cDNAs
zinc finger |  | Lists zinc finger mRNAs
breast cancer |  | Lists mRNAs associated with breast cancer susceptibility proteins
evans |  | Lists mRNAs deposited by scientist named Evans
Murphy,K.E. |  | Lists mRNAs deposited by co-author K.E. Murphy
Use this last format for author queries. Although GenBank requires the search format Murphy KE, internally it uses the format Murphy,K.E..

### Assembly Details

The dog genome contains approximately 2.5 billion base pairs. This sequence is based on 7.6X coverage of the dog genome, assuming a WGS assembly size of 2.4 Gb. The assembly has an N50 contig length of 123 kb and an N50 supercontig length of 41.6 Mb. The boxer breed was selected for the initial sequencing effort based on the lower variation rate in its genome relative to other breeds. For more information about this assembly, see the NHGRI press release.

The canFam1 sequence and annotation data can be downloaded from the UCSC Genome Browser FTP server or downloads page.
