These Webpages are no longer maintained. We are keeping the pages here to preserve some of the early years of ProjectDragonfly, to honor the students who created the interactives in the early days of the Web, and because many of the activities are fun and people are still using them.

Did you know that everything in your body is a trait that is passed down from your parents?  That includes your ear lobes.  That's right, the ear lobes that you have depend on what ear lobes your parents have.

There are two types of ear lobes: free, or attached.
They look like this:
 
 

Free ear lobes is the dominant trait and attached ear lobes is the recessive trait.  We will use a big "F" to represent the dominant trait and we will use a small "f" to represent the recessive trait.

Using what you have already learned about simple trait inheritance from the Mendel page, match this girl with her parents.
 

This girl has attached ear lobes.
 

Attached ear lobes is a recessive trait.

Remember that for the recessive trait to be expressed, the person must have two recessive traits.
