MULTILOCUS DYNAMICS UNDER HAPLOID SELECTION

A general haploid selection model with arbitrary number of multialleli c loci and arbitrary linkage distribution is considered. The populatio n is supposed to be panmictic. A dynamically equivalent diploid select ion model is introduced. There is a position effect in this model if t he original haploid selection is not multiplicative. If haploid select ion is additive then the fundamental theorem is established even with an estimate for the change in the mean fitness. On this basis exponent ial convergence to an equilibrium is proved. As rule, the limit states are single-gamete ones. If? moreover, linkage is tight, then the sing le-gamete state with maximal fitness attracts the population for almos t all initial states.
