Describe how researchers analyze orthologs to construct phylogenetic trees.

Introduction:

Phylogenetic tree also called an evolutionary tree is a branch-like pattern that appears as a tree exhibiting the evolutionary relationships among the individuals belonging to various species of the biological world. The study is based on the differences and similarities in their physical, anatomical, or genetic characteristics.

Orthologs: These are genes present in different species that are known to be evolving from a common ancestor, and have diverged due to speciation. Orthologs hold back the same function as the species undergo the process of evolution.
