Clarify Question
· What is the key concept addressed by the question?
         o This question addresses cladistics.
· What type of thinking is required?
         o This question is asking you to analyze the information given, using logic, to dissect the problem and determine the answer.
· What key words does the question contain and what do they mean?
         o Traits are features of an organism, used as data to build a tree.
         o Extant species are still alive – i.e., not extinct.
         o The ancestral condition of a trait is the original condition; the derived condition is the more newly evolved version.
         o Plesiomorphies are ancestral characters.

Gather Content
· What do you already know about cladistics?
         o Cladistics is the method used to construct a cladogram — a graphically represented hypothesis of evolutionary relationships.
         o Only shared derived characters (synapomorphies) are useful for inferring phylogenies, and they must be contrasted to an outgroup that has the ancestral characters.

Consider Possibilities
· What other information is related to the question? Which information is most useful?
         o A plesiomorphy is an ancestral character, so the question is asking which trait is most often in the ancestral condition in this data chart.

Choose Answer
· Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer?
         o The ancestral state is marked as “0” in this chart, so the trait represented by the most plesiomorphies is E (with 4/6).
   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?
         o This question asked which of the traits is represented by the most pleiomoprhies.
         o The question required you to analyze the information given, using logic, to dissect the problem and determine the answer.
         o Did you recognize that the trait with the most “0”s was the one with the most pleiomorphies?

26

Which group of terms refers to the microsporophyll, the male portion of a flower?

27

Sickle cell anemia is a condition in which red blood cells exhibit a characteristic "sickle" shape. This arises from a mutation or change in one of the amino acids found in hemoglobin. A single amino acid mutation would directly affect a protein's _______ structure.
