Don't fall into the trap of thinking that these percentages are the
simple result of counting markers and dividing by the maximum
possible score. It's nowhere near that simple. In fact, it is
quite possible for a child to exceed the sum of both parents on
one ethnicity. I'd guess the excess could be as much as 15% if
things fall out just right.
