28.B
The random X-inactivation which occurs early in a developing female can result in skewed or non-random X-inactivation for a patch, tissue or organ.
During the process of X-inactivation one of the female's two X chromosome is inactivated.
This becomes important in medicine when a carrier female of an X-linked recessive condition 'randomly' inactivates the chromosome containing the unaffected gene. This can lead to mild symptoms of the disease
