Concepts

The proportion of phenotypic variation in a trait that is due to genetic variation, estimated using parent-offspring regression methods

When previously adaptive traits become maladaptive due to rapid environmental change, such that organisms are attracted to resources that reduce their fitness

Genetic variation maintained in populations by natural selection where different alleles are favored under different conditions

The degree to which novel resources resemble historical resources in their chemical or physical cues

Genetic change in a trait if there is heritable variation, selection, and heritability
