Variation in genome size in 50 selected DGRP strains with atypical genome sizes.

The mean genome size for D. melanogaster females is 175.5 Mb. N = Number of females. Mb = Megabase. s.e. = Standard error of the mean in Mb. Significance groups (A, B, C, D, etc.) differ at P<0.05 by a Duncan test. Average genome size - mean = deviation from the mean (175.5 Mb). t-test to the mean of 175.5 Mb determined significant (P<0.05) variation from the mean. Note that some strains were not significantly different from the mean due to their high variance in genome size.
