Drosophila genome assemblies with D. melanogaster DNA
Figure 1 shows DNA coverage of species assemblies to D.melanogaster genome, size of species assembly and counts of inverted segments. Coverage for earlier assemblies(asm1) along with latest assemblies are shown.

Figure 2 shows DNA coverage as percent of D.mel. chromosomes.

Figure 3 shows inverts to the D. melanogaster chromosomes. Inverts are counted as changes in strand within each scaffold, so are affected by completeness of assembly as well as chromosomal inversions. This likely correlates with chromosomal inversions, but isn't an exact measure of those.
Notes:
  • In Figure 1, Dgri asm1 is better by a measure of Dmel dna coverage than asm2. Dmel asm1 size includes heterochromatin; only euchromatin was used for DNA matches.
  • The Dsim assembly used here is dgpg-2004 (syntenic) as the 2005 wu-mosaic has some yeast genome contamination. The Dyak assembly used here is from NCBI, removing about 25MB in ChrU of yeast genome contamination, shown in an earlier version of Figure 1.
  • This comparison uses a BLASTn cutoff of 1e-5 for genome assembly DNA to Dmel genome. M Data are from ftp://eugenes.org/eugenes/genomes/
  • Year 2005 new assemblies for Dyak and Dpse were added 21 Nov 05.
