This article has been posted to your Facebook page via Scitable LearnCast. For genes that are specific to the X chromosome and that escape X-chromosome inactivation, female cells with two X chromosomes may contain higher levels of the gene product than male cells, which have only a single X chromosome. Microarray experiments indicate that the sex-specific differences in gene expression are quite extensive. It turns out that the sex determination pathway is probably more complicated and SRY may in fact inhibit some anti-male genes. Mind Read. Vive la difference: Males vs. In this Page. In any case, the simple fact of X-chromosome inactivation leads to two levels of difference between males and females.

Techniques that allow the transgene to be specifically inactivated in a tissue of choice offer ways to bypass these problems because the gene can be expressed normally except in the tissue where it is being studied.
