9. Using a key Di- chotomous = 2 parts usually “yes”/”no” responses Look at page A56 at the dichotomous key Answer the  question

10. 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.
