NotesA characteristic that a living thing gets from its parents is called an inherited trait.

A learned behavior is a skill that an animal develops after it is born.

Learned behaviors are not passed from parents to their offspring. If you know how to ride a bike, your children will not be born knowing how to do that. They will have to learn, just as you did.

Like learned behaviors, some physical traits are not inherited. If you cut your hand and get a scar, you will not pass that trait on to your children. A bird with a broken wing will not have offspring with broken wings. A tree may be bent by the wind or scarred by lightning. But seedlings that grow from the tree’s seeds will not have those traits.

A.Walking on four legsB.Rolling over on commandC.Barking D.panting
