WebHow and why female somatic X-chromosome inactivation (XCI) evolved in mammals remains poorly understood. It has been proposed that XCI is a dosage-compensation mechanism that evolved to equalize expression levels of X-linked genes in females (2X) and males (1X), with a prior twofold increase in expression of X-linked genes in both sexes … WebDosage compensation is a way to equalize or balance the expression of genes.

WebThe question of the reality of the existence of heterochromatin dose compensation, on the example of human chromosomal Q-HRs, we believe proven. In this case, can we assume that XCI and Q-HRs dose compensation in the genome of women are of the same nature? Our answer: Yes, rather than no. There are few arguments in favor of such a point of view.
