Explore trait diversity by taking an inventory of easily-observable genetic traits in a group of people such as your class. Observe how your trait inventories differ from those of others. Record your observations in a data table and make a bar graph to show the most and least common traits in the group. 

Traits are physical characteristics that are inherited from our parents. In this activity we will look at traites that are easily-observable.

To start, take a look at these example traits

For each trait below, note which form you have.

add your data to a section that matches this lesson in your notebook. (ex. earlobe = attached)

For earlobes only, how many students in your class do you think will share the same form (free or attached) as you?

How many of your classmates do you think will have the same form of all seven traits as you?

Traits are observable characteristics that are passed down from parent to child. Take inventory of some easily observable genetic traits.
