You expected a clear answer from a molecular biologist?

That probably depends on all sorts of things, like relative amounts
of tissue of host and zoox, which depends on species, and zoox
abundance, which varies in response to environment (bleaching being
the extreme case...). "It depends...." - That's why no one can give
you a clear answer.
For what it's worth, there's enough zoox and host DNA in any one
sample to cause you a genuine headache. If you're wanting to
sequence something, make sure you've got damn good specific primers.
If you're looking to make a library, then either use isolated zoox in
culture or zoox free tissue - sperm, or eggs for some spp.
