Genomic relationship among and between the large and small genome groups.

<p>(<b>A</b>) A heat map depicting the genomic relationship between DGRP lines. Genome size is ordered decreasingly from left to right and bottom to top. The strains in the groups are indicated as the red and blue rectangles on the top of the heat map. (<b>B</b>) Histograms showing genomic relationships within and between the genome size groups.
