Im aware of this from an old cannonical point of view, but for one rogue trader is only considered semi-canon at the moment. And 2, from analysis of what we know about genetic engineering at 2013, breeding an eldar female and a human male would result in a hybrid (like cross breeding a tiger and lion to create a liger) and as the deviation allowance for a gene seed is extremely narrow, an eldar hybrid would not be able to become a space marine.
