Flow cytometry estimates of the mean diploid genome size of the different karyotypes investigated (based on 3 replicate measures). Canton-S and 2549 measure are from reference22.
**
The approximate heterochromatin content for the strains investigated is indicated, assuming that the euchromatic size is constant for all chromosomes (i.e. 233.8Mb for flies with 2 X chromosomes, and 211.9Mb for flies with a single X chromosome, see Fig. 1A).
