In humans and flies, males and females have different set of sex chromosomes contributing to different levels of X-linked gene expression. To equalize X-linked gene dosage between sexes, both humans and flies developed independent strategies which are called dosage compensation. Human females randomly inactivate one of their X chromosome into barr body and Drosophila males up regulate their single X chromosome two fold. Both strategies equalize of X linked gene dose between sexes.
In Drosophila, dosage compensation is brought about by the ribonucleoprotein Male Specific Lethal (MSL) complex that binds hundreds of sites along the X chromosome and modifies …
