So the volatility of certain elements governs the process of whether a planet will be similar or different in composition to its host star, but there is no direct correlation between a star's mix of elements and that found on the gas-rich planetary bodies. One would expect based on earlier theorizing that the star's composition would be reflected in both gas giants and rocky planets but alas this is not the case.
