Look around is anyone just like you? You and everyone else are unique. No two people are exactly alike, including identical twins. many of your traits are inherited. You are going to identify some of your genetic or inherited traits. You will then use this data to trace who in the family you are most alike.

Resources Needed: You will need to have as many family members as you can answer the questions on the various work sheets. Chart data and compare to your data.
