Abstract
A two-site, infinite allele model is used to study the influence of intragenic recombination on the effective number of neutral alleles maintained in a hybrid population. It is shown that the combination of intragenic recombination and hybridization can have a large effect on the effective number of alleles maintained in a population at equilibrium and an even larger effect when the population is not at equilibrium. When the mutation and recombination rates are large, a completely subdivided population will not maintain as much variability as a random mating population. It is concluded that unique alleles in hybrid populations could be formed by intragenic recombination.
