What scientist would use a dichotomous key?
Answer: Many scientists use dichotomous keys to identify plants, animals, and other organisms.

However, dichotomous keys are not used only to identify organisms.
Can multiple dichotomous keys be developed to identify the same group of organisms?
Is it possible to create more than one dichotomous key for classifying and identifying the same group of objects? Explain. Yes, it is possible. Different dichotomous key creators may think of different characteristics to classify.
How do you create a dichotomous key?

What are the two types of dichotomous keys?
Types. There are two types of dichotomous keys….The advantages of a polyclave (multiple-access) key are:
- easy to use;
- multi-entry – meaning the user can start anywhere.
- order-free – meaning the user can work in any direction with any character;
- faster (sometimes); and.
- easily computerized.
What happens if a key creator confuses one species as two?
