### Sample position queries

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 Pika genome. See the User's Guide for more information.

Request: |  | Genome Browser Response:
--- | --- | ---
chrZ |  | Displays all of chromosome Z
chr3:1-1000000 |  | Displays first million bases of chr 3
chr3:1000000+2000 |  | Displays a region of chr 3 that spans 2000 bases, starting with position 1000000
BX950328 |  | Displays region of mRNA with GenBank accession number BX950328
BU335953 |  | Displays region of EST with GenBank accession BU335953 on chr Z
pseudogene mRNA |  | Lists transcribed pseudogenes, but not cDNAs
homeobox caudal |  | Lists mRNAs for caudal homeobox genes
zinc finger |  | Lists many zinc finger mRNAs
kruppel zinc finger |  | Lists only kruppel-like zinc fingers
zhang |  | Lists mRNAs deposited by scientist named Zhang
Taguchi,T. |  | Lists mRNAs deposited by co-author T. Taguchi
Use this last format for author queries. Although GenBank requires the search format Taguchi T, internally it uses the format Taguchi,T..

### Assembly details

The genome has been sequenced to ***X coverage. Approximately 88% of the sequence has been anchored to chromosomes, which include autosomes 1-24, 26-28, and 32, and sex chromosomes W and Z. (In contrast to mammals, the female chicken is heterogametic (ZW) and the male is homogametic (ZZ).) The remaining unanchored contigs that could be localized to a chromosome have been concatenated into the virtual chromosomes "chr*_random", separated by gaps of 10,000 bp. Unanchored contigs that could not be localized to a chromosome have been concatenated into the virtual chromosome "chrUn", separated by gaps of 1,000 bp in order to reduce the total size of chrUn. The chicken mitochondrial sequence is also available as the virtual chromosome "chrM".

Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or the Downloads page. *** Developer -- remove this if no conditions for use: These data have specific conditions for use. The Pika browser annotation tracks were generated by UCSC and collaborators worldwide.
