Imagine that you work for a company that specializes in ornamental flowers. One spring, you find an ornamental tobacco plant with beautiful lavender flowers, a color you are sure will be in high demand. Knowing that tobacco plants are self-pollinating, you harvest seeds from it. A test plot of the seeds planted the following season fails to impress your boss. 31 of the 106 test plants have white flowers. You want to develop seeds guaranteed to produce only lavender flowers.
Describe the problem that must be solved to make the lavender flowered plants a commercial success.
