Week 7 "Genes "R" Us"

 Week 7

"Genes "R" Us"

 

This week we continued our exploration of genetic traits.  This time students looked at some of their own phenotypes and determined the frequency of various traits in our class. We charted frequency of several phenotypes such as: (Hairline, Earlobes, Freckles, Hair Type, Tongue roller, Hitchhiker's thumb, PTC Taster) After charting data in groups, we combined our data into a class frequency chart. We compared our data to see if our phenotypes really



                                  were accurate with the dominant or recessive information we

                                 discussed earlier.  Each group also explored a Hardy Weinberg

                                 equation to determine our actual frequency (percentage) of

dominant and receive traits in this class.  (As you can see from the pictures finding our you are a PTC taster is an interesting experience!) Ha Ha!!!
