Genetic, Cytological and Genomic Map Coordinates for D. melanogaster Genes
FlyBase offers a downloadable spreadsheet that lists the genomic coordinates, cytological (polytene band) position and genetic map position for all annotated D. melanogaster genes. Information for each chromosome arm is available on a separate tab of the spreadsheet. For both cytological and genetic map positions, we report both experimentally determined values reported in the literature as well as FlyBase computational estimates. For genetic map positions, we also provide an alternative computational estimate based on the mapping of millions of SNPs from thousands or recombination events Comeron et. al., 2012.
D. melanogaster Chromosome Maps
Site is in progress. Files will be available with the new FB2016_04 release, currently scheduled for May 24, 2016 (i.e., links to .png files don't work just yet).
Table 1. The original illustrations of D. melanogaster polytene chromosomes by Bridges and Slizynski.
| Species | Chromosome | Muller Element | References | File |
|---|---|---|---|---|
| D. melanogaster | X | A | Bridges 1938, Bridges 1935 | Dmel_X_Bridges.png |
| D. melanogaster | 2L | B | Bridges 1942, Bridges 1935 | Dmel_2L_Bridges.png |
| D. melanogaster | 2R | C | Bridges and Bridges 1939, Bridges 1935 | Dmel_2R_Bridges.png |
| D. melanogaster | 3L | D | Bridges 1941, Bridges 1935 | Dmel_3L_Bridges.png |
| D. melanogaster | 3R | E | Bridges 1941, Bridges 1935 | Dmel_3R_Bridges.png |
| D. melanogaster | 4 | F | Slizynski 1944 | Dmel_4_Slizynski.png |
Table 2. The original electron micrographs of D. melanogaster polytene chromosomes by Lefevre. High magnification electron micrographs of individual D. melanogaster polytene chromosome bands are available from Saura, Saura and Sorsa, University of Helsinki. These electron micrographs offer an alternative reference for checking polytene band references.

| D. melanogaster | 4 | F | Lefevre 1976 | Dmel_4_Lefevre.png |
Table 3. Annotated D. melanogaster chromosome maps that combine illustrations and electron micrographs with annotation of the genomic, genetic and cytological positions indicated for select genes. Note that for the Y chromosome, the micrograph shown is of a prometaphase mitotic chromosome. Note also that large genome assembly gaps are not depicted in GBrowse, and so Y chromosome genes look closer together than they really are.
