This statement is totally false because random X inactivation occurs in the early female embryo development. During early female embryo development, both the maternal and the paternal X chromosome have an equal chance of becoming inactivated. Then, inactivated X chromosome condenses into a compact structure called a Barr body,and this X-chromosome maintained in a silent state.

Which of the following statements is TRUE about X inactivation? A. Inactivation of a particular X chromosome depends on its genetic content. Inactivated X chromosomes are in some way "marked" such that all clonally related cells (daughter cells) have the same X chromosome inactivated. B. Inactivation of an X chromosome occurs at random early in embryonic development. Inactivated X chromosomes are in some way "marked" such that all clonally related cells (daughter cells) have the same X chromosome inactivated. C....

D Question 22 Identify a FALSE statement about X chromosomes: a) X chromosome inactivation occurs in all somatic cells of females. b) Xist inactivates only the maternally inherited X chromosome. The inactiveX chromosome is coated with Xist transcripts. di X chromosome inactivation does not occur in males. In early cleavage stage embryos, both X chromosomes are active.

(True or False) Fragile X syndrome is thought to be caused by the inactivation of a gene spanning the fragile region on the X chromosome due to a large number of trinucleotide repeats just upstream from the coding sequence of the gene.
