Dandelions develop seeds by apomixis. What benefits does this strategy provide over vegetative or sexual reproduction?
A. Apomixis makes the dandelions more resistant to herbicides.
B. Apomixis provides the benefits of seed dispersal, while maintaining a genome adapted to a given climate.
C. Apomixis is beneficial in sheltered areas where wind pollination would be difficult.
D. Apomixis is beneficial for plants that attract a diverse mix of bees and other pollinators.

Clarify Question
What is the key concept addressed by the question?
· This question is asking about the advantages of apomixis, which is a form of asexual reproduction.
What type of thinking is required?
· Analyze level:
o This is an analyze question because you have to break the characteristics of apomixis into their component pieces to understand how they function.

What do you already know about apomixis? What other information is related to the question?
· Apomixis is asexual reproduction.
· Rather than forming gametes through meiosis, in apomixis, clones of diploid cells form the embryo.
· Apomixis requires only one parent.
· The products of apomixis are seeds.

Given what you now know, what information is most likely to produce the correct answer?
· The process of apomixis is essentially cloning; the offspring would only be herbicide-resistant if the parent cell was herbicide-resistant.
· The offspring produced by apomixis would be identical to the parent, so there would not be a diverse variety of plants to attract a diverse variety of pollinators.
· Offspring produced by apomixis would be adapted to an environment as their parent was adapted to that environment.
· An advantage of apomixis is that in the production of seeds, dispersal is a possibility.
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?
· Analyze level:
o Answering this question correctly depended not only on distinguishing between apomixis and other forms of reproduction, but on your ability to analyze the outcomes of apomixis. If you got an incorrect answer, did you remember that components of apomixis include the production of clones of the parent, or that the seeds that result from apomixis would be available to disperse away from the parent? Did you have trouble breaking down the nature of offspring produced by apomixis to determine the correct answer?
