Location of centromeric and centromere-proximal satellites in D. melanogaster.

Locations of satellites on chromosomes X, Y, 2, 3, and 4 according to previous reports and our observations in this report by IF-FISH in the D. melanogaster sequenced strain iso-1. Each satellite location is characterized as being centromeric (overlaps with CENP-C), pericentric (juxtaposed to CENP-C), or heterochromatic (more distal than pericentric). Note that the dodeca satellite includes its variants and that Prodsat is also known as the 10-bp satellite.
