Developing a Dichotomous Key

• At each step this key asks the reader to decide
  which of two statements best describes the
  organism he or she is trying to identify. The
  reader then moves on to the next pair of
  statements until the organism is identified.
  Many dichotomous keys contain simple yes/no
  questions about a particular trait.

A yes/no question
If yes, continue
If no, stop here
As you keep isolating traits, the identifying
characteristic becomes evident.
