Innate Behavior and Genetics

Innate behavior is instinctive and inherited through DNA, not requiring learning or practice. It is intrinsic, stereotypical, inflexible, and consummate, meaning it is fully developed at birth. Examples include reflexes and behaviors like web-spinning in spiders. Research shows that innate behavior has a genetic basis, as seen in aggressive mice studies. Environmental factors can influence these behaviors, but they remain largely unchanged. Innate behavior is subject to natural selection, with advantageous traits becoming more common over time.

What is an example of innate behavior mentioned in the video?

• A cat being trained to use a litter box

• A spider spinning a web

• A dog learning to fetch

• A parrot mimicking human speech

Which of the following is NOT a characteristic of innate behavior?

• It is heritable

• It is stereotypic

• It is flexible

• It is intrinsic

How is innate behavior beneficial according to the video?

• It is subject to natural selection

• It is always complex and difficult to understand

• It allows for quick adaptation to new environments

• It can be easily modified through learning

What does it mean for behavior to be intrinsic?

• It is learned from others

• It is present even in isolation

• It changes with experience

• It is unique to each individual

What is a reflex action as described in the video?

• Learning to ride a bicycle

• Pulling away from a hot object

• Training a dog to sit

• Teaching a child to read

What was the main focus of Lars' experiment?

• To show that mice can be peaceful

• To demonstrate the genetic basis of aggression

• To prove that aggressive behavior is learned

• To train mice to solve mazes

What did Lars' experiment reveal about aggressive mice?

• They were unaffected by genetic selection

• They became less aggressive over time

• They were more likely to avoid fights

• They inherited aggressive traits

Which characteristic of innate behavior means it is fully developed at first performance?

• Consummate

• Stereotypic

• Intrinsic

• Heritable

Which of the following is a characteristic of innate behavior?

• It is flexible and adaptable

• It is influenced by cultural factors

• It requires practice to develop

• It is performed the same way every time

What does it mean for behavior to be heritable?

• It is learned from the environment

• It is unique to each individual

• It is passed down through DNA

• It changes with experience
