The final cross of this group involves the nature of pea seed coats. If you cross true breeding plants with smooth (wild) skins with those that breed true for wrinkled skin, the F1 are all smooth. Selfing the F1 produces an F2 in which the coats are divided between smooth and wrinkled. Run the program several times until you are sure of your data. Then test it with the Chi Square program. Remember, RESET clears all the windows. SELFED when repeatedly activated clears only the windows of the immediate cross.
