Inherited and Learned
Behaviors
Traits (Behavior)
• Traits are something an organism does.
• Examples:
A bear hibernating
Plant stems growing up and roots growing
down
Inherited Traits
• Characteristics passed down to an
offspring by his or her parents.
• These traits (behaviors) are controlled by
genes made up of DNA.
Examples of Inherited Traits
• Hibernation-a deep sleeplike state when
an animal’s body processes slow down.
• Migration-seasonal movement of animals
from one place to another
• Protecting Young
• Walking
• Eating
• Breathing
Examples of Inherited Traits

Which one is inherited?
Learned Behavior
• A learned behavior is a behavior that an
animal develops by observing other
animals or by being taught.
Examples of Learned Behaviors
• Sea animals doing tricks
• Birds avoiding viceroy butterflies
Learned and Inherited
• Some behaviors animals have are a
combination of learned and inherited traits.
• Examples:
Young cheetahs have the instinct to hunt,
but at first do not know how to sneak up
on their prey. They learn how to do that
by watching their mother when she hunts.
Wolves have the instinct to hunt but learn to
hunt in groups.

Plant’s Behavior
• All plant behavior
is inherited (they
can’t learn can
they?).
• However, plants
will respond to
their
environment.
Plants responding to their
environment
• A plant’s response to
a stimulus is called
tropism.
• If you put a plant
near a window it will
turn it’s leaves
toward the sunlight.
• Plants roots grow
downward toward
water.
Questions
What is the difference between
a learned behavior and an
inherited trait?
An inherited trait is something
that is passed down to the
offspring by the parents.
A learned behavior is something
the organism acquired by
watching or being taught.
