You have fewer male ancestors than female ones.

Is there evidence for this, or is it just something inferred from what we know about gender power dynamics and the like?

As for evidence, it seems plausible, as mitochondrial DNA and Y-Chromosomal DNA come respectively from our mothers and fathers. And so, I could imagine an analysis of mutation drift relative to known rates of mutation could make an inference on this over generations.

Explain.

Edit: (I feel like I figured out your meaning but will wait for your response)

father-daughter incest or similar

You have a unique female for every generation of your family tree, but males can show up more than once

edit: thought of a situation where you could have a female repeat (a woman and her son.. she'd be mom and grandma to those offspring). so I don't know. YMMV on this one.
