It sounds ridiculous. How do they know that these six people are in any way descended from relatives of Leonardo da Vinci? It’s been 700 years. It would serve to prove that the people were not related to da Vinci if none of them matched the bones.

“The Y chromosome, passed on to male descendants, is known to remain almost unchanged through 25 generations. Comparing the Y chromosome of today’s male relatives with that of their ancestors in ancient and modern burial sites would both verify the uninterrupted family line and certify Leonardo’s own Y chromosome marker.”

If the Y chromosomes from the six men are all identical, it is good evidence their research is correct, and they are all relatives of Leonardo.

The chances of all six having identical Y chromosomes from another source seems pretty small.

Not zero, but pretty small.
