All of the tissue of XY males have to suffer the results regarding a good mutation for the an X-chromosome-connected gene, but simply that fraction out of a woman’s tissues you to carry the newest mutation with the productive X chromosome would be impacted. For example factors has resulted, sometimes, for the solid somatic options against cells you to sustain the brand new mutation towards new active X-chromosome which means avoidance (or minimization) of the state phenotype (Belmont, 1996; Willard, 2000).
It ought to be indexed that the stochastic character of initially assortment of and therefore X-chromosome so you can inactivate are determined by of several facts. Environment, epigenetic, and you will genetic factors have the ability to already been demonstrated to determine the fresh new X-chromosome inactivation pattern (this new ratio from a beneficial woman’s structure with a specified productive X chromosome) out of private lady (Puck and you will Willard, 1998).
