In corn, purple kernels (P) are dominant over yellow kernels (p) and round kernels (R) are dominant to wrinkled kernels (r). 

 

In a cross of PpRr (purple, round) with a pprr (yellow, wrinkled) plant, the following progeny were observed:

 

Phenotype

Observed

Expected

(O-E)

(O-E)2/E

Purple, Round

117

 

 

 

Yellow, Round

126

 

 

 

Purple, Wrinkled

130

 

 

 

Yellow, Wrinkled

127

 

 

 

 

Total=500

 

 

 

 

Fill out the expected values in the chart above and calculate the Chi-Square value for your table, look up the p value associated with the Chi-Square. 

 

  1. How many degrees of freedom do you have in this cross?

 

2. What is your Chi Square value? 

 

3. What is the p value for this cross and what does your value mean? Make sure to explain the p value clearly in a couple of sentences.
