what is represented by the base roof of a phlogentic tree

Sagot :

Answer:

Ancestral linkage

Explanation:

A phylogenetic tree or a phylogeny, in other words, is a diagram that outlines the history of evolutionary descent of different species, organisms, or genes from a single lineage or shared ancestor.

A phylogenetic tree is typically drawn from the bottom upwards or from the left to the right.

Phylogenetic trees can either be rooted or unrooted. To be rooted means that there is a single ancestral linkage or lineage. Unrooted phylogenetic refers to multiple ancestral linkages.
