    OK there's some Y-chromosome genes that only ever see a male (and
    mitochondrial genomes that only ever get *passed on* by females - that's
    a bit weird though), but 99.9% (er...) of our genes are there in both
    sexes all the time. What I'm getting at is how would the evolution of
    memes be different when there is a route which treats the other gender
    as a foreign species - sons get male behaviours from dads, daughters get
    female behaviours from mums.

    Actually the only stuff that I can really see (off the top of my head)
    going this route is the life skills stuff like personal hygiene, and
    some rather unsavoury sexist stuff. If I was trying to get evolutionary
    about it I suppose I'd expect these single gender memes to evolve more
    quickly than those exploiting the whole, rather than half, of the
    available grey matter out there (evolution happens faster in small
    populations which is why Americans have accents closer to the C17th than
    Brits do), but that will be confounded by too much stuff to get a clear
    picture (for example, if the behaviours relate to external stuff that
    doesn't change it's harder to estimate the effect).
