Is Behaviour genetically inherited?

All behavior has heritable components. All behavior is the joint product of heredity and environment, but differences in behavior can be apportioned between hereditary and environment.

Is behavior genetic or environmental?

Behavior is best seen as the result of evolutionary processes that sometimes create, through genetic coding, behavioral instructions for animals and at other times create flexible mechanisms to allow animals to solve problems specific to their environment.

You may have heard of the so-called First Law of Behavior Genetics: All human behavioral traits are heritable.” Turkheimer coined this and two further “laws” to point up ironies in the way behavior genetics was being practiced.
