Question

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 (purple, round) plant, the following progeny were observed:

 

Phenotype

Observed

Expected

(O-E)

(O-E)2/E

Purple, Round

288

 

 

 

Yellow, Round

90

 

 

 

Purple, Wrinkled

95

 

 

 

Yellow, Wrinkled

Total=500

 

 

 

a.  What is the expected ratio for PpRr X PpRr plant?  You can use a punnett square to find the expected ratio.  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.   

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

c.  What is your Chi-Square value? 

d.  What is the p value for this cross
