The difference in the expression of X-linked genes between human females and female Drosophila. Introduction: The female carries two X chromosomes whereas male carry one X chromosome. Thus, the presence of two X chromosomes result in formation of double amount of protein. This difference in the amount of proteins can be detrimental because concentration of proteins play major role in the development. Thus, the inactivation of one X chromosome in female is necessary. Some animals have overcome this by evolving the mechanism refers as dosage compensation.
