How does a tiger have stripes?
It turns out that this was a question that was answered by Alan Turing in the 1950s. 

Turing hypothesized there would be two morphogens, an inhibitor/ activator pair, each of which would produce a one of two phenotypes by activation or suppression of a trait.  He hypothesized that this would produce a pattern like stripes or other patterns (e.g. black and orange stripes).  

This year just such inhibiting/activating pairs produce patterns like ridges in the top of the mouth of mice.  

In a broad way, this seems like X-inactivation, where there is an X-inactivation center (XIC) that is inhibited or activated when the cell is created in mitosis.  XIC is still hypothetical and undiscovered, but it can create patterns and is non-random. 

So I would say that this tiger stripes and X-inactivation may share Turing's mechanism, but the stripes, found in male and female tigers alike is not linked causally to X-inactivation.
