We perform a study of the final-state interactions of the 
and the 
systems in the reactions and . The interactions of the mesons are accounted for by using chiral unitary techniques, which generate dynamically the a
0(980)-resonance, and the interaction is also taken into account. The amount of 
versus
production is shown to depend critically on the primary mixture of the two mechanisms, with large interference effects due to final-state interactions
