These Webpages are no longer maintained.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.

That's Right!
Even though one of the parent has the dominant trait of dimples, the other parent does not.  That means that there is a two in four chance that the offspring will not have dimples.  That's half.

Now we're going to get tough.

Can you roll your tongue?  If you can that means that you have the dominant trait.  If you can't roll your tongue, that means that have the recessive trait.  We'll use a big "R" to represent the dominate trait of tongue rolling and a small "r" to represent the recessive trait of non-tongue rolling.

Instead of giving you a picture of what the girl looks like, we're only going to give you punnent squares.  Do you think you can match the offspring with the parents?

The girl can't roll her tongue.

Choose the punnent square or squares that could be possible matches with the girl and her parents?  As in the other punnent squares, the parents are on the outside (Dad on top, mom on side) and the possible offspring are inside.

Pick a squre and find out if you were right.
