Which of the following statements about X-inactivation is FALSE? A) X-inactivation results in a Barr body. B) X-chromosome inactivation equalizes the gene dosage between mammalian male and females. C) Once a cell undergoes X chromosome inactivation, all of its daughter cells will have the same X chromosome inactivated. D)The X chromosome inherited from the father is always inactivated. E) The process of X-inactivation could explain why females that are heterozygous for an X-linked recessive disorder might display some of the phenotype of that disorder.
