I failed to get the concept of the bold following part:
So if we are genetically disposed to develop synaesthesia, does that rule out the possibility of inducing the experience?

The word 'does' is part of the expression.
Synaesthesia is something that scientists are interested in, so of course they want to study it. It would be easy to study it if we could induce some people to experience it (perhaps by giving them a drug that gives them synaesthesia). Therefore, scientists would be very happy if there's a possibility of inducing it.
However, it seems that synaesthesia is genetic. If that's true, it could prevent or otherwise rule out the possibility of inducing synaesthesia. But we're not sure, it might not rule it out.
That's why the author is asking us the open question: Does it rule out the possibility of inducing synaesthesia?
