All mesons and baryons consist of quarks. 

Quarks and anti-quarks in Standard Model classification of subatomic particles.

Anti-quark is different from quark, opposite charge, opposite quantum numbers.

That's not what swansont said:

He meant "neither quark mentioned by you" (up/down)..

(but other strange/charm/top/bottom and their anti-particle equivalents)

So the source could still be a quark then?

He meant neither up nor down quarks. It is obvious from the context.

It can be. Or a lepton.

Are we to conclude then that the force carriers of the weak interaction originate only from within both quarks and leptons?

In other words, all fermions ("matter particles").
