Rapid gene change via behavior
Using several behavioral models, the researchers show that the Pten-mutant mice have deficits in social learning and interaction. For example, the mutant animals spent less time investigating the social target (a new mouse) compared with controls. When presented with a choice between the social target and an inaminate object, the Pten mutants spent similar amounts of time interacting with both. When the social target was removed and later re-introduced, the mutant mice, unlike their normal counterparts, did not reduce their interaction with it, indicating that they might have impaired social learning.
Our genes, like our environment, merely increases probabilities of certain states of affairs or behaviors without determining anything specific.
