We study diploid branching particle models and its behaviour when rapid
stirring, i.e. rapid exchange of particles between neighbouring spatial
sites, is added to the interaction. The particle models differ from the
``usual'' models in that they all involve two types of particles, male
and female, and branching can only occur when both types of particles
are present. We establish the existence of nontrivial stationary
distributions for various models when birth rates are sufficiently large.
