In one of Mendel's dihybrid crosses, he observed 315 round yellow, 108 round green, 101 wrinkled yellow, and 32 wrinkled green plants. Analyze these data using the test to see if

(a) they fit a 9:3:3:1 ratio.

(b) the round:wrinkled data fit a 3:1 ratio.

(c) the yellow:green data fit a 3:1 ratio.

HINT: This problem involves an understanding of analysis, as used to determine whether a specific dataset fits certain ratios. The key to its solution is to first determine the expected outcome for each predicted ratio. Then, following a stepwise approach, determine the deviation in each case, and then calculate and interpret each value.
