What is a gene tree and how does it illustrate the evolutionary relationships among different gene sequences?
A gene tree is a diagram that shows the evolutionary relationships among different gene sequences. It illustrates how genes have changed and diverged over time, similar to a family tree showing relationships between relatives. By comparing gene sequences from different species, scientists can create gene trees to understand how genes have evolved and how species are related to each other.
