 Genes from this bacterium have been placed into plants vulnerable to caterpillars and the insects proceed to die when they eat part of the plant, as they consume the toxic protein.Thus developmental approaches must be assessed on a case by case basis and in Sesardic's view, DST does not offer much if only posed in general terms.Psychologist Linda Gottfredson differentiates the "fallacy of so–called "interactionism"" from the technical use of "gene-environment interaction" to denote a non–additive environmental effect conditioned upon genotype.
