Miles:
I think this statement and the discussion about it has no basis in canon or
in JKRs statements.
We do not know *anything* about the nature of magic in Potterverse. We do
not know why people are magical and others are not, we do not know anything
about magical "theory" or the nature of spells and their power. JKR doesn't
explain, or better: she makes Harry being absolutely uninterested in it.

So it's pure speculation to assume that genetics play any role for humans
being magic or not. I agree, that genetics of old Mendel won't work with it
at all. We could write loads of mails about how it doesn't work, but again,
there is no canon support for the existence of anything like genetics in the
Potterverse.

Miles, who forgot most of what he had to learn about genetics for his
university-entrance diploma. Seems to be recessive knowledge.
