You expect % of your sample (total # of kernels) to be purple e₁ = your sample (total #) multiplied by 4 (round to the nearest whole number and record in the table) b. You expect 1 of your sample (total # of kernels) to be yellow e₂ = your sample (total #) multiplied by 4 (round to the nearest whole number and record in the table) 8.

X² = the symbol for the term, chi-square
o = observed count (number) (01 = the number of purple, 02 = the number of yellow)
e = the expected number according to the predicted ratio. All en must be calculated for your
sample
To calculate the expected numbers for your 3:1 monohybrid cross:
a. You expect % of your sample (total # of kernels) to be purple
e₁ = your sample (total #) multiplied by 4 (round to the nearest whole number
and record in the table)
b. You expect 1 of your sample (total # of kernels) to be yellow
e2 = your sample (total #) multiplied by 4 (round to the nearest whole number
and record in the table)
8. Now use the formula to calculate the chi-square value X² and show your work.
