That's not quite fair to evolution: crossover is vastly more important to real world evolution than mutation (even as mutation is critical to create the raw material that's crossed). I don't think I ever have seen a GA application that made prior use of crossover, because most use genotype->phenotype codings that can't even in theory make it useful. That's where anyone young starting on this road should start.
