For a science assignment a student was asked to observe some organisms and then make a table to classify the organisms’ traits as inherited or learned. The student’s table is shown below.

Observations of Some Organisms

Trait Inherited or Learned?

1. Colt able to walk right after birth...................?

2. Student texting a message.............................?

3. Spider spinning a web.................................?

5. Child using a fork to eat.............................?

6. Woman driving a car...................................?

7. Green leaves on a tree................................?

8. Lion jumping through a hoop...........................?

How many of these observations describe learned behaviors and how many describe inherited traits?

• 1 learned behavior, 7 inherited traits

• 2 learned behaviors, 6 inherited traits

• 3 learned behaviors, 5 inherited traits

• 4 learned behaviors, 4 inherited traits

Some traits of living organisms are inherited, while some behaviors must be learned.

Which statement related to inherited traits or learned behaviors is NOT correct?

• The ability of a figure skater to spin on ice is related to both inherited traits and learned behaviors

• the ability of lions to use camouflage to hide in grassy fields is an inherited trait only

• the number and type of legs a cricket has is an inherited trait only

• a bird builds a nest is a learned behavior
