title: A two loci viability matrix with implications in current population genetics models.
abstract: Some equilibrium properties of a two loci deterministic system subject to a postulated viability matrix are given. Two conclusions are reached: i) linkage can not stabilize additive equally contributing two-loci systems under optimizing selection. ii) Hybrid protein superiority can not be invoked for the maintenance of polymorphisms shared by duplicated structural loci.
