Question

Which is the best definition of a phylogenetic tree?

A)a table of classification that is based only on physical characteristics

B)eight levels of taxonomic categories that are used to classify organisms

C)a branching chart that depicts evolutionary relationship among organisms

D)organisms organized based on structure and genetic comparisons

Answer 1

The correct answer is C. A branching chart, that depicts evolutionary relationship among organisms.

Phylogenetic tree is termed as branching diagram and shows evolutionary relationship which is among different biological species.

All phylogenetic tree indicates common ancestry. In phylogenetic tree it has nodes which are known as taxonomic unit and there are those which are internal and referred to as hypothetical taxonomic units.

In biology trees are used as phylogenetic systematics and as bioinformatics.

Answer 2

A phylogenetic tree is a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics.

So the best choice is C)a branching chart that depicts evolutionary relationship among organisms
