Document Summary

53. 2 how do genes and environment interact to shape behaviour: genes do not encode behaviours. Rather, gene products such as enzymes can affect behaviour by setting in motion a series of gene-environment interaction that underlie the development of proximate mechanisms that enable individuals to make certain behavioural responses. Experiments can distinguish between genetic and environmental influences on behaviour: www. notesolution. com: 2 experimental approaches that are useful to biologist in evaluating how genes and experience interact to shape behaviours: In a deprivation experiment, investigators rear a young animal so that it is deprived of all experience relevant to the behaviour under study. If it still exhibits the behaviour, may assume that the behaviour can develop without opportunities to learn it. Experiment showed that hereditary underlies the food-storing behaviours of the tree squirrel species, but the behaviour was expressed only when the environment provided conditions that stimulated the behaviour (the presence of a nut).
