Barton, N.H., 1986: The maintenance of polygenic variation through a balance between mutation and stabilizing selection. The maintenance of polygenic variation through a balance between mutation and stabilizing selection can be approximated in two ways. In the 'Gaussian' approximation, a normal distribution of alleic effects is assumed at each locus. In th...

Hastings, A., 1990: Maintenance of polygenic variation through mutation-selection balance: bifurcation analysis of a biallelic model. Biallelic models which ignore linkage disequilibrium have been used to study variability maintained by mutation in the presence of Gaussian stabilizing selection. Recent work of Barton (1986) showed that these models have stable equilibria at whic...

Zhang, X-Sheng.; Hill, W.G., 2002: Joint effects of pleiotropic selection and stabilizing selection on the maintenance of quantitative genetic variation at mutation-selection balance. In quantitative genetics, there are two basic "conflicting" observations: abundant polygenic variation and strong stabilizing selection that should rapidly deplete that variation. This conflict, although having attracted much theoretical...

On the basis of single-locus models, spatial heterogeneity of the environment coupled with strong population regulation within each habitat ( soft selection) is considered an important mechanism maintaining genetic variation. We studied the capaci...

Bürger, R., 1989: Linkage and the maintenance of heritable variation by mutation-selection balance. The role of linkage in influencing heritable variation maintained through a balance between mutation and stabilizing selection is investigated for two different models. In both cases one trait is considered and the interactions within and between...

Zhang, X-Sheng.; Wang, J.; Hill, W.G., 2002: Pleiotropic model of maintenance of quantitative genetic variation at mutation-selection balance. A pleiotropic model of maintenance of quantitative genetic variation at mutation-selection balance is investigated. Mutations have effects on a metric trait and deleterious effects on fitness, for which a bivariate gamma distribution is assumed. E...

The infinitesimal model is extended to cover linkage in finite populations. General equations to predict the dynamics of the genetic variation under the joint effects of mutation, selection and drift are derived. Under truncation and stabilizing s...
