Exercise 11

Two four-o'clock plants were crossed and gave the following offspring: 1/8 crimson, 1/8 orange-red, 1/4 magenta, 1/4 magenta-rose, and 1/4 white. Unfortunately, the person who made the crosses was color blind and could not record the flower colors of the parents. From the results of the cross, deduce the genotypes and flower colors of the two parents.
