Question
student crosses a pure-breeding line of red-flowered poinsettias with a pure-breeding line of
white-flowered poinsettias. The student observes that all the pants in the F1 Generation have pink
flowers. The student then crosses the F1 plants with one another and records the observations about
the plants in the F2 generation. The student will use the F2 data to perform a chi-square goodness of
fit test for a model of incomplete dominance. The setup for the student's chi-square goodness of fit
test is presented in table 1.
a.

The calculated chi-square value is 1.53, and the null hypothesis cannot be rejected.
The calculated chi-square value is 1.53, and the null hypothesis can be rejected.
The calculated chi-square value is 98, and the null hypothesis cannot be rejected.
d. The calculated chi-square value is 98, and the null hypothesis can be rejected.
