Don’t know, but it would appear to be quite difficult to accomplish. Humans are quite mixed genetically, and we share so many common ancestors even just 10 generations back (e..g, you and I have a good chance of sharing an ancestor 10 generations back, and by 20 generations back almost certainly we have someone in common.)
It would seem easier to use behavior rather than genetics.
For example, if you poisoned batches of Lutefisk, few Italians would be affected.
