• Have you ever asked yourself  questions about your own appearance? 


• Have you wondered why you do or don't look like other family members? 


• Maybe you are sick of aunty Grizelda telling you how much you resemble your uncle Bert, her late husband (which would be especially bad if you were a girl!).


• You might want to know more about heredity - how you inherit your various characteristics.


• Then again maybe the teacher told you that you had to come here and read all this stuff.


• Anyway, the guys below have questions or things they want to say. Just pass the cursor over their faces to see what they want to say. (You don't need to click and you might have to wait a few seconds at first).
