Any process that modulates the frequency, rate or extent of gene expression; the process is mitotically or meiotically heritable, or is stably self-propagated in the cytoplasm of a resting cell, and does not entail a change in DNA sequence. Compensating for the two-fold variation in X:autosome chromosome ratios between sexes by a global activation or inactivation of all, or most of, genes on one or both of the X chromosomes. The aggregation, arrangement and bonding together of proteins on DNA to form the complex that mediates dosage compensation on both X chromosomes in the monogametic sex, ultimately resulting in a two-fold reduction in transcription from these chromosomes. An example of this process is found in Caenorhabditis elegans. Compensating for the two-fold variation in X:autosome chromosome ratios between sexes by an inactivation of a proportion of genes on both of the X chromosomes of the XX sex, leading to a decrease, of half, of the levels of gene expression from these chromosomes. An example of this process is found in Caenorhabditis elegans.
