To get a pure bred colored, you choose several colored flower plants, and let them self-fertilize, then you plant and grow the seeds. Many of the self-fertilized plants have some colored and
some white flower offspring. You choose one of the plants from a family of all colored flower
plants, let it self-fertilize, then you plant and grow its seeds. All the plants you get have colored
flowers. Now what?

A. This colored flower
plant is pure-bred.

B. This isn't a pure-bred plant, you
need to start all over again.

C. The white flower plant (after it self-
fertilizes) will give pure-bred colored
flowers in the next generation.
