Custom Visualization of Chromosomal Mapping from Whole Genome Shotgun Sequencing

"This image represents a window into evolutionary chromosomal dynamics across a set of closely related species (eight species of Drosophila melanogaster, or fruit fly) that shared a last common ancestor approximately 40-60 million years ago. The image illustrates genome-scale changes, which enables us to investigate rates of rearrangement on an evolutionary time-scale, constraints on genome shuffling, and the role of rearrangements in the process of speciation, among other things."
