Acquired vs. Inherited Traits
Characteristics = Traits A characteristic of an organism may be inherited or acquired. You are a unique individual. Characteristics about you are called traits. Examples: Eye color, basketball skills
Inherited Traits Received from your biological parents Examples: natural eye color, hair color, height, blood type.
Acquired Traits Developed during life (not born with it) Examples Things you learned (riding a bike, reading, writing) Things that happened to you (short hair, cut-off finger)
Acquired traits end with you! CANNOT pass on acquired traits to offspring NOT in DNA/genes! Example: Your kids won’t be born with a missing arm if you cut off your arm first!
Some traits are both! Skin color is a combination trait Inherited part: Receive genes for skin color from parents. Acquired part: Amount of time in the sun determines level of tan.
Let’s Practice! Take out a sheet of notebook paper and number it 1 -12. For each example, write down whether you think the trait is acquired or inherited. Think: “Was this organism programmed from birth to have this trait? ”
Example: Dimples Is this an acquired trait or an inherited trait?
Dimples – Inherited Trait! This child has genes from her parents that gives her dimples.
