There's a huge huge difference between 'memory' and 'instinct'. DNA passing on ancestral memory is Science Fiction - go read Frank Herbert's Dune. Instinct on the other hand can be encoded - go look up the reflex actions of babies, or better yet, go look at porn and see what happens to your 'johnny'.

It would require rapid, non-random mutation of the DNA within an individual for it to carry memories as in the examples given by the TS, something that doesn't happen.
