question 27 of 36
to be useful for phylogenetic reconstruction, a taxonomic character must exhibit which properties? select all that apply.
□ it must be anatomical.
□ it must be molecular (dna or protein).
□ it must have a genetic basis.
□ it must vary among the taxa being analyzed, but not within individual taxa.
□ none of the other answer options is correct.

Explanation:

For phylogenetic reconstruction, a taxonomic character must have a genetic basis to be heritable and show evolutionary relationships. It should vary among the taxa being analyzed to distinguish them, but be consistent within individual taxa to be reliable. It doesn't have to be only anatomical or only molecular.

Answer:

It must have a genetic basis.
It must vary among the taxa being analyzed, but not within individual taxa.
