title: Simultaneous Stability of D=0 and D not equal0 for Multiplicative Viabilities at Two Loci.
abstract: The two-locus, two-allele multiplicative viability model is investigated. It is shown that the well-known region of recombination values for which D = 0 is locally stable does not preclude the local stability of an equilibrium with D not equal 0. This is shown numerically and is true for every case investigated in which both loci are overdominant and the viabilities not symmetric.
