Question

Identify the parts of a cladogram using the drop-down menus.


Label A

Answer 1

I don’t have the cladogram image, so I can’t tell which part A is pointing to. Could you either upload the image or describe where A is pointing (for example: at an endpoint/tip, at the intersection where two lines split, on a line between splits, at the very base, on a bracket grouping several taxa, or next to a tick mark on a branch)?

To help you choose from the drop-downs, here are the usual label meanings:

- Tip/terminal taxon (terminal node): the endpoint of a branch representing an extant or sampled taxon.
- Branch/lineage: the line connecting nodes and tips; represents an evolutionary lineage.
- Node (internal node): the point where a branch splits; represents a common ancestor.
- Root: the base of the tree representing the most recent common ancestor of all taxa shown.
- Clade (monophyletic group): a group consisting of an ancestor and all its descendants (often shown by a bracket or a shaded region).
- Sister taxa: two taxa (or clades) that share an immediate common ancestor (i.e., two branches off the same node).
- Derived character / synapomorphy: a trait shown on a branch or tick that is shared by a clade.

If you tell me which option A might be pointing at (or paste the drop-down choices), I’ll pick the correct one.
