Abstract: The Fleming-Viot process associated to a killed normally reflected diffusion Xt is known to provide a particle representation for the quasi-stationary distribution of Xt. In this paper we establish three results for this particle system. We firstly establish that it also provides a particle representation for the principal right eigenfunction of the submarkovian infinitesimal generator of Xt. Secondly we establish that the Fleming-Viot process provides a representation for the Q-process. Thirdly we prove a conjecture due to Bieniek and Burdzy on the asymptotic distribution of the spine of the Fleming-Viot process and its side branches. We obtain these as corollaries of the following result. The Fleming-Viot multi-colour process is obtained by attaching genetic information to the particles in the Fleming-Viot process. We establish that under a suitable rescaling it converges to the Fleming-Viot superprocess from population genetics, with spatial inhomogeneity having the effect of speeding up the rate of genetic drift according to a simple formula.
