Sounds like you are speaking of Barr bodies. In the somatic cells of women you have two XX chromosomes. If both these chromosomes were allowed to express gene product you would have big problems with too many proteins doing, or trying to do the same job. So, randomly from cell to cell, these superfluous chromosomes are methylated and inactivated so only one X is expressed somaticly in women.

How do you show that 2 sin squared x minus 1 divided by sin x minus cos x equals sin x plus cos x?
(2 sin^2 x - 1)/(sin x - cos x) = sin x + cos x (sin^2 x + sin^2 x - 1)/(sin x - cos x) =? sin x + cos x [sin^2 x - (1 - sin^2 x)]/(sin x - cos x) =? sin x + cos x (sin^2 x - cos^2 x)/(sin x - cos x) =? sin x + cos x [(sin x - cos x)(sin x + cos x)]/(sin x - cos x) =? sin x + cos x sin x + cos x = sin x + cos x
What is 1-x divided by x squared plus x?
1 - x/(x2 + x) = 1 - x/[x(x+1)] = 1 - 1/(x+1) = (x+1)/(x+1) - 1/(x+1) = x/(x + 1)
How do you simplify x cubed minus x?
x^3-x = x(x^2-1) = x(x+1)(x-1)
