G x e interactions: physiological systems: the purpose of these types of systems are to integrate sensory input and decide on relevant behaviour; dependent on. Receives sensory input, without which you have no idea what behaviour to make. Ex: to know when to run away from danger (also requires hormonal system) Hormone systems: slower acting, make certain actions more or less likely.

These systems need to exist in an individual so it can make appropriate behavioural responses to sensory input. The genes you inherit can make this more or less likely (increase or decrease fitness). By doing so, they influence how many copies of those genes are passed on to the next generation.
