This says it very clearly!
Contrary to the impression given by certain articles, the latest DNA evidence does not repeat not demonstrate that there was illegitimacy in the line of descent from Edward III to Richard III. It demonstrates it either there or in the line from Edward III to the present Duke of Beaufort. (The latter line, being longer, is statistically more probable, but that’s as much as we can say.)
In addition the present queen is not impacted in any way, as she is sovereign by statute. Specifically the Act of Settlement of 1701, which gives the throne to descendants of Sophia, Electress of Hanover. Her descent from Sophia is not involved in the DNA ‘chain’ in question.
Any information to the contrary is ‘spherical objects’.
