Drosophila simulans Assembly and Gene Annotation
About Drosophila simulans
Drosophila simulans is, in evolutionary terms, closely related to D. melanogaster, and was one of 12 fruitfly genomes sequenced for a large comparative study . In addition to comparison with the exceptionally well-studied D. melanogaster, D. simulans is useful for research into speciation due to its close relationship with D. sechellia and D. mauritiana . Ensembl Genomes imports data from FlyBase, who also have much more information about the biology of Drosophila simulans, and a phylogeny of the 12 sequenced fruitfly species.

The ASM75419v3 assembly of Drosophila simulans is a chromosome-level assembly with a genome size of ~125Mb .
Repeats were annotated with the Ensembl Genomes repeat feature pipeline. There are: 196,738 Low complexity (Dust) features, covering 16 Mb (11.8% of the genome); 40,696 RepeatMasker features (with the RepBase library), covering 16 Mb (11.5% of the genome); 61,523 Tandem repeats (TRF) features, covering 5 Mb (3.6% of the genome).
Protein domains were annotated with the Ensembl Genomes protein feature pipeline.
