Question

difference between phylogram and phenogram?

Answer 1

Explanation:

phylogram :

1. A phylogram is a branching diagram (tree) that is assumed to be an estimate of a phylogeny.
2. The branch lengths are proportional to the amount of inferred evolutionary change.
3. A cladogram is a branching diagram (tree) assumed to be an estimate of a phylogeny where the branches are of equal length.

phenogram :

1. a branching diagrammatic tree used in phenetic classification to illustrate the degree of similarity among taxa — compare cladogram.
2. phenogram A type of dendrogram which is based on phenetic data (see PHENETIC CLASSIFICATION).
3. Lines called phenon lines, drawn at right angles to the dichotomously branching dendrogram, represent lines of percentage similarity of phenetic features between organisms.

◆ Difference between cladogram & phenogram.

➻ Both cladogram & phenogram are the methods of building photogenic trees.

➻ Cladogram rely on ancestral assumptions while phenogram don't take evolutionary history into account.

➻ Branch lengths provide no data in cladogram but are very important in phenograms.

➻ Cladograms emphasize more on ancestral relationships and phenograms emphasize more on current relationships.
