Overview of Muller Elements in Drosophila Genomes

These maps show large scale synteny between genome assembly units (scaffolds or chromosomes), as determined from genome x genome DNA BLAST matches, identified as common Muller elements A thru E (small F/Dmel-chr4 is not listed).

Muller's elements are the names A,B,C,D,E,F for six chromosome arms common among Drosophila species as coined by Hermann Müller. Chromosome names and centromeric joins differ among the species; Muller elements identify the common units. See below for D. melanogaster chromosome correspondence. Data for these analyses are available at /species/data/dros-synteny-data/

Each chromosome picture has the query genome on the left as a "ladder" from bottom base 1 to top end, and the synteny source on the right as an arrow. Between are colored lines of high matching regions (colors distinguish clusterings). Weaker syntenic relations are not shown. Lack of display doesn't mean lack of synteny.
The "top segments" links display the largest scaffolds (> 1MB) or chromosomes in size order, with associated synteny if any. Map hyperlinks now go to GBrowse map of entire segment. If interest warrants it, regional map sections can be linked in.
