I'd be curious how much of my personality
is genetically determined by my part Jewish DNA...???

But such tests can't answer this, and the question itself might be pure nonsense
based on bad science...

I occasionally refer to this wiki entry,
because it is a question that would have mattered significantly in Europe in the 1930s and 40s...

It would potentially have meant life or death...

This subject has preoccupied me since my late teens,
and to an extent influence my choice of studying a Humanities degree nearly 40 years ago...
