TIL that even if both parents are left-handed, the chances of their child being left-handed is only about 20-26%.
I.e. even for lefty parents, it's far more likely to have a right-handed child.
I knew it wasn't pure Mendelian genetics (the numbers don't work out), but I was expecting something like 60-70% in favour of left-handedness there.
