Theoretical Analysis of Habitat Selection and the Maintenance of Genetic Variation
Habitat selection is often suggested as a factor that may result in easier maintenance of genetic polymorphisms (e.g., Hedrick, 1986 and references therein). However, habitat selection may take several different conceptual forms, some of which appear to greatly broaden the conditions for a polymorphism while others have a much smaller impact. In particular, habitat selection based on homing that is independent of genotype has only a marginal influence on the conditions for polymorphism (e.g., Hoekstra et al., 1985) while models that are based on genotypic-specific habitat selection may greatly broaden the conditions for a genetic polymorphism.
