Chi Square Analysis

Reminder: do not forget to state your alternative and null hypothesis!

Determine the most probable genetic crosses based on the following data:

Two lines of true-breeding plants, one with yellow petals and one with red, are crossed. The Fis are all red. When an Fi is selfed, the following offspring are produced:

Red:
259

Yellow:
61

Use X^2 analysis to determine whether the data fits your proposed hypothesis.
