segregation which states that there are pairs of particulate factors which control each trait and they segregate during gamete formation and then come together randomly at fertilization. The second Law‚ the law of independent assortment states that the inheritance of a certain gene is not affected by another gene on another chromosome. This current experiment is a replica of Mendel’s and it will show how his ideas still apply to nowadays phenomena. 1.2 OBJECTIVES: The objectives of the experiment are:

touch are scattered over the surface of your entire body‚ however those receptors are more closely grouped together in certain parts of your body. In this activity you will investigate the distribution and sensitivity of the touch receptors in the human body. Procedure 1. Obtain 8 large paperclips‚ a ruler‚ and masking tape. 2. Bend paperclip to form a “U” or “V” shape so the ends are 1/2 centimeter apart. 3. Put masking tape across the “legs” of the paperclip to maintain the end
