A baby bird inherits information that causes it to grow feathers as it gets older.  This inherited information is known as

An adult rose plant with pink flowers passes this trait to its offspring.  If the offspring gets enough sunlight and water, it will

• sprout brown leaves
• grow pink flowers
• have pale flowers when it grows
• be much shorter than its parents

Which of these is an example of an inherited trait?

• A frog has green skin with spots.
• A frog lives in the same forest as a brown hawk.
• A frog has a scar on its leg from a cut
• A frog finds a new home after a big flood

• A tadpole growing legs as it develops.
• A dog being skinny because of a disease.
• A pig being large because it eats too much food.
• A goat having a broken horn because of a fight

• All of the above

________ is an example of an inherited trait affected by the environment.

• A baby bird growing feathers
• A tadpole growing legs as it develops

Which of the following statements about traits is false?

• Traits are affected by both genes and environment
• Only diseases can cause an inherited trait to change
• The environment can affect both plants and animals
• Inherited genes tell an organism what to do as it grows.

________ is an example of a trait passed by genes.

• Size of a pig
• Color of a flower
• Type of feather
• All of the above

A plant growing a flower as it gets older is an example of 

• an inherited trait
• a learned behavior
• an environmental change
• a non-inherited trait

What are genes?

• traits that are not inherited from an offspring's parents
• changes in the environment that affect how an animal grows
• inherited information that tells offspring what traits to have
