Definition
Compensating for the two-fold variation in X-chromosome:autosome ratios between sexes by a global hyperactivation of all, or most of, the genes on the X-chromosome in the heterogametic sex, leading to a two-fold increase in gene expression from this chromosome. An example of this is found in Drosophila melanogaster.
