Answer:
1. Rooted tree
Make the inference about the most common ancestor of the leaves or branches of the tree.
2. Un-rooted tree
Make an illustration about the leaves or branches and do not make any assumption regarding the most common ancestor
3. Bifurcating tree
This tree has a maximum of two descendants arising from each of the interior nodes.
4. The multifurcating tree
This tree has multiple descendants arising from each of the interior nodes.
It is defined as a diagrammatic representation of evolutionary relationships among living organisms. This diagrammatic representation represents how different species evolved from a series of common ancestors.
The phylogenetic tree can also be defined as the two-dimensional graph representing the evolutionary relationship between an organism from various other organisms.
The phylogenetic tree is also called the “Tree of Life” or “Dendrogram” The idea of a phylogenetic tree arose from an ancient concept of a ladder-like progression from moderate to powerful forms of life. The term Phylogenetic or Phylogeny is derived from the ancient Greek word, which refers to race, origin or lineage.
