Clarify Question
What is the key concept addressed by the question?
· The question is asking about the consequences of self-pollination.
What type of thinking is required?
· Apply level:
o You are being asked to take what you already know and apply it to the effects of self-pollination to a plant and the plants in the surrounding area.

What do you already know about pollination? What other information is related to the question?
· Both pistils and stamens are found in the same flower on a self-pollinated plant.
· Self-pollinated plants have lower genetic variability than cross-pollinated plants.
· Self-pollination is favored in environments that have greater stability.
Choose Answer
Given what you now know, what information is most likely to produce the correct answer?
· Self-pollinated plants are not necessarily more resistant to garden pests or diseases.
· If self-pollinating plants are grown next to each other, they maintain their own identities and traits, so different varieties could be easily differentiated.
· To turn a self-pollinator into a cross-pollinator, the stamens must be removed.
Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o Answering this question correctly depended on your ability to use the characteristics of self-pollinating plants in a new situation. If you got an incorrect answer, did you remember that self-pollination removes the necessity for dispersion, or that self-pollinated plants maintain their own unique identities? Did you have trouble extending the characteristics of self-pollinated plants to determine the correct answer?
