"Like father like son" is a common phrase that we hear when a boy looks a lot like his father.  Have you ever wonder why?  Up to this point, we have discussed about nucleus, chromosome, and DNA.  As you recalled from the previous entry, DNA is the genetic make-up of your body.  Specifically, there are sections on the DNA called genes that determine your traits.  For instance, there is a particular section on your DNA that determines your eye color, hair color, and you name it.

In this activity, I want you to take a close look at some of your traits.  Record your results on another sheet of paper.

1.  Can you roll your tongue?

2.  Can you make a Vulcan hand sign?

3.  Are you right- or left-thumbed?  Put your hands together, interlocking your fingers.  Which thumb is on top?  Write “right” or “left.”

4.  Do you have dimples?  Look into a mirror and smile.  Do you see any?

Go to your mom and dad.  Ask them these questions and record the result from both of them.  Compare your result to your parent's.  Can you tell who passes on the trait to you?  Reply your conclusion under the "Comments" section.
