Examples of differences observed in normalization methods. a Boxplots of individual RAL-320 males of Environment 2. b Boxplots of the coefficient of variation for RAL-900 females of Environment 3. c Boxplots of the coefficient of variation for RAL-900 males of Environment 3. A complete set of box plots can be found in Additional files 2 and 3. Abbreviations for normalization methods are the same as defined in Fig. 1. It has come to our attention that the line number designation for the Drosophila Genetic Reference Panel has been officially changed in Flybase. Specifically, the lines used to have a “RAL-” prefix; they now have “DGRP-” as the prefix (for example, “RAL-320” is now “DGRP-320”). We have used the “RAL-” prefix several times in our manuscript, in Fig. 3, and in Additional files 2 and 3. Future usage would be with the “DGRP –“prefix
