Why are so many Rh negatives left-handed?

Why are so many Rh negatives left-handed? https://www.datebytype.com/pictures/index/190/Left-handed-celebrities Many of them can be found here: When asking who is Rh negative and left-handed (not me, but one member), 2 out of 5 stated they are left-handed: https://www.facebook.com/groups/rhnegatives/?post_id=2251528338448052 I have noticed similar results on the old fan page. This is not an official study and if there was one, it wouldn’t make it into the medical journal until we have an explanation the editors accept. What could be the reason? Why are Rh negatives more likely to be left-handed? Are you left-handed or right-handed and what is your blood type? (Note: Many have answered with “ambidextrous” and for now, I am counting these votes as “neutral”)
