No links please, and thank you in advance :) Can someone give me an example of a dichotomous key, I have learned a little about it.. but I’m still a little confused. Can I have an example?

important scientific tool used to identify different organisms, based the organism's observable traits

Explanation:

consist of a series of statements with two choices in each step that will lead users to the correct identification

For example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.

Example objects to identify: apple tree, water-lily, fir tree, dandelion, astroturf, seaweed. Dichotomous keys may be simple or complex depending on what is being identified. I hope this helps

Explanation:

clinically, some people often have repeated allergies, eczema and respiratory infections or other parts of the infection, in this case, in addition to some routine tests such as tests for white blood cells, immunoglobulin series, lymphocyte subsets, etc., the five immune immunoglobulin tests are also necessary.
