In Drosophila, dosage compensation is controlled differently than in humans. In human females one X chromosome is silenced so that each cell produces proteins from just one X chromosome, as in human males. In fruit fly females both X chromosomes remain active. In fruit fly males, dosage compensation is carried out by the male-specific lethal (MSL) complex (consist of MSL proteins and roX RNAs). Based on what you know about dosage compensation, the role of MSL complex in fruit fly males would be to
