C
Dendrogram
D
Cladogram
Verified step by step guidance1
Understand the different types of phylogenetic trees: Phylogram, Chronogram, Dendrogram, and Cladogram. Each type represents evolutionary relationships but emphasizes different aspects.
A Phylogram is a type of phylogenetic tree where the branch lengths are proportional to the amount of evolutionary change. This means it highlights where evolutionary changes occur along the branches.
A Chronogram is a phylogenetic tree where the branch lengths represent time, showing the timing of evolutionary events rather than the amount of change.
A Dendrogram is a general term for a tree diagram used to illustrate the arrangement of the clusters produced by hierarchical clustering. It does not specifically highlight evolutionary changes.
A Cladogram is a type of phylogenetic tree that shows the relationships between different species but does not represent the amount of evolutionary change or time. It focuses on the branching order.
