The data displayed on the Ensembl Fruitfly Drosophila melanogaster site is a compendium of data from the Berkeley Drosophila Genome Project (BDGP), FlyBase and the Drosophila Heterochromatin Genome Project (DHGP). The genomic sequence is the BDGP assembly, release 5 (April 2006).
The genome assembly represented here corresponds to GenBank Assembly ID GCA_000001215.1
The annotations are imported from FlyBase release 5.46 (FB2012_04, dated 6 July 2012). No additional gene build has been carried out, however BLAST hits and protein features have been computed, and cross-references to other data sources were updated in Ensembl release 70 (January 2013).
The Ensembl Fruitfly Drosophila melanogaster variation database has been produced using data from release 1.0 of the "50 genomes" data set from the Drosophila Population Genome Project. The data set contains over 6.7 million SNPs from two populations, one comprising 37 lines from north Carolina and the other comprising 15 lines from Malawi.
This species (and other invertebrates, including 11 other drosophilid species) are also available from our sister site, Ensembl Metazoa

|Golden Path Length|
The golden path is the length of the reference assembly. It consists of the sum of all top-level sequences in the seq_region table, omitting any redundant regions such as haplotypes and PARs (pseudoautosomal regions).

Genes and/or transcript that contains an open reading frame (ORF).
|Small non coding genes|
Small non coding genes are usually fewer than 200 bases long. They may be transcribed but are not translated. In Ensembl, genes with the following biotypes are classed as small non coding genes: miRNA, miscRNA, rRNA, scRNA, snlRNA, snoRNA, snRNA, and also the pseudogenic form of these biotypes. The majority of the small non coding genes in Ensembl are annotated automatically by our ncRNA pipeline. Please note that tRNAs are annotated separately using tRNAscan. tRNAs are included as 'simple fetaures', not genes, because they are not annotated using aligned sequence evidence.
A pseudogene shares an evolutionary history with a functional protein-coding gene but it has been mutated through evolution to contain frameshift and/or stop codon(s) that disrupt the open reading frame.
