I think your second theory is easier to argue than the first - if there is a
set magical quanta, then it would follow that the more wizards there were,
the weaker they would be magically, because the magic would be spread
thinner. The idea of "contagion" is I think a sound alternative to the
genetic theory - because wizards have magic, then their offspring are more
likely to contract it, muggle foetuses would only contract it occasionally.

Sadly I doubt that canon will ever enlighten us on this one!
