Gene Trees

Gene trees are diagrams that show the evolutionary relationships of specific genes across different species or individuals. They illustrate how particular genes have changed and diverged over time, revealing patterns of common ancestry and genetic history. Unlike species trees, which map the evolution of entire species, gene trees focus on a single gene or gene family, allowing scientists to study gene evolution, duplication, and transfer events. They help us understand how genes evolve within and between species, providing insights into genetic diversity and evolutionary processes.
