1. Human Genetics We surveyed our class to see how many students showed dominant or recessive traits. The seven traits surveyed were, mid-digit hair, pinky, color blindness, dimples, forelock, thumb, and types of ear lobes. These results along with the rest of the results submitted by students in the project were analyzed. Is the dominant trait most prevalent?

3. Process & Results We totaled # of people surveyed and totals for each trait. We decided if the dominant or recessive trait was present for each of the 7 traits examined in this project. We graphed our findings on excel.

4. What we know about ear lobes Free ear lobes are (d) Attached ear lobes are (r) (d)=dominant ®=recessive

5. More things about Ear Lobes is… Dominant ear lobes are free ear lobes. Dominant ear lobes are those that hang below the point of attachment to the head. Recessive are attached ear lobes. Attached ear lobes are attached directly to the side of the head.

17. Our Conclusion The Recessive Traits were more common. Poplar Bluff 5/6 Grade Center Ms. Carda’s 6 th grade homeroom Poplar Bluff, MO

18. Ideas for the future If we were to do this study again, we’d like to survey such traits as: Left/right handed Tongue rolling and Hair color
