It is not clear whether you realise it, so I'll point it out: the Y
chromosome, while it indeed does really show "relatedness" in the
everyday sense (because in fact it carries very few working genes),
is passed on in near perfect copies from father to son, and so it is
very useful for trying to trace one ancestral line out of the
thousands we have, and therefore it is useful for studying ancient
migrations, especially males are felt to have played a key role.

Mitochondrial DNA, similarly, is passed from mothers to children.
