multiple choice 6.15 points\nwhat is the purpose of including an out - group in a phylogenetic tree analysis (phylogenetic analysis)?\nto present a control in case evolution has not occurred\nan out - group should not be included in phylogenetic analysis\nto present the most derived states of any taxa considered\nto present a taxa with all ancestral states for informative characters/features

multiple choice 6.15 points\nwhat is the purpose of including an out - group in a phylogenetic tree analysis (phylogenetic analysis)?\nto present a control in case evolution has not occurred\nan out - group should not be included in phylogenetic analysis\nto present the most derived states of any taxa considered\nto present a taxa with all ancestral states for informative characters/features

Answer

Brief Explanations:

In phylogenetic tree analysis, an out - group is a taxon that is outside the group of interest. It is used to root the tree and to help determine which traits are ancestral and which are derived. It represents a taxon with all ancestral states for informative characters/features.

Answer:

To present a taxon with all ancestral states for informative characters/features
