Dichotomous Key Maker: Two-Choice Identification
A dichotomous key maker turns observable traits into a two-choice identification guide with clear branches and labeled endpoints.
How to test every branch
A dichotomous key is a decision tree built from observations. Its branches should ask one focused either-or question at a time, such as whether a leaf has lobes or whether an edge is toothed. The goal is a traceable path from an object to an endpoint, not a decorative tree with ambiguous choices.
Use a defined set of specimens and a small legend for yes/no branches. The dichotomous key maker creates an editable draft for classroom examples; verify every trait against a field guide before using it for real identification.
A focused review workflow
Read both options at every node and follow every route to an endpoint. If a specimen can satisfy both choices, rewrite the trait before adding more branches.

A practical prompt
Create a dichotomous key for four fictional leaves. Use yes/no questions about lobes, edge texture and shape, keep connectors noncrossing and end every path at a labeled leaf. State that the examples are fictional.
Common questions
What makes a good dichotomous key trait?
It should be observable, consistent and useful for separating the remaining choices.
Can I use a generated key for real species?
Use it as a planning draft and verify it against a trusted taxonomic source or field guide.
