Is cranial shape actually useful for grouping human variation?

Update:

What are some features that can aid in the determination of ancestry in the skull?

I am trying to prove that human genetics and morphological variation does not fit into groupings of race or continental origins. Is is actually useful for human variation?

    Not very

    We all have 23 pairs of chromosomes, so most traits are always passed-on independently from skullshape - and the others can be unlinked by "crossing over"

    Yes it is and it has been used for some time now. The entire skull not just the cranium. 

    However dna testing is more the norm these days.
