In an early Gregor Mendel’s study, he crossed two hybrid pea plants and recorded the
form (round or wrinkled) and albumen color (yellow or green) of the fertilized seed. He
theorized that these should appear in the following proportions
Round, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green
         9/16                    3/16                3/16                  1/16

The observed counts were as follows:
Round, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green Total
          315                    101                108                     32             556

0.  What are the expected counts?
Round, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green Total
                                                                                                     556

Test to see if the observed counts confirm Mendel’s theory. Use ? = 0.05.
1. State the null and the alternative hypothesis using the proper notation established in class.
