Detailed explanation-1: -A fixed action pattern is a predictable series of actions triggered by a cue, sometimes called the key stimulus. Though a fixed action pattern is more complex than a reflex, it’s still automatic and involuntary. Once triggered, it will go on to completion, even if the key stimulus is removed in the meantime.

Detailed explanation-2: -Fixed action patterns are behavioural sequences that occur as a result of innate releasing mechanisms. For example, when a dog sees a cat running away from them, they have an instinctive response to chase the cat.

Detailed explanation-3: -There are 6 characteristics of fixed action patterns. Fixed action patterns are said to be stereotyped, complex, species-characteristic, released, triggered, and independent of experience.

Detailed explanation-4: -Behavior that is developmentally fixed is called innate behavior. Innate behavior is controlled by genetics. These behaviors produce responses that are automatic without any prior experience. Several animal movements are innate, meaning they are genetically programmed. These behaviors are often in response to stimuli.
