Question
In four o’clock plants, many flower colors are observed. In a cross
involving two true-breeding strains, one crimson and the other
white, all of the F1 generation were rose color. In the F2, four new
phenotypes appeared along with the P1 and F1 parental colors.
The following ratio was obtained:
1/16 crimson
2/16 orange
1/16 yellow
2/16 magenta
4/16 rose
2/16 pale yellow
4/16 white
Propose an explanation for the inheritance of these flower
colors.
