Genealogical processes for Fleming-Viot models with selection and recombination

Infinite population genetic models with general type space incorporating mu tation, selection and recombination are considered. The Fleming-Viot measur e-valued diffusion is represented in terms of a countably infinite-dimensio nal process. The complete genealogy of the population at each time can be r ecovered from the model. Results are given concerning the existence of stat ionary distributions and ergodicity and absolute continuity of the stationa ry distribution for a model vith selection with respect to the stationary d istribution for the corresponding neutral model.
