Explanation / Answer
Chi-Square value= 7.49
Degrees of freedom= number of phenotypes - 1
= 2-1=1
Reject null hypothesis.
Phenotype Observed (O) Expected(O) O-E (O-E)^2 (O-E)^2/E
Violet flowers 687 696.75 -9.75 95.06 0.14
White flowers 242 232.25 9.75 95.06 0.41
Chi-Square value= 0.55
Degrees of freedom= number of phenotypes - 1
= 2-1=1
Fails to reject null hypothesis.
