What is comparative gene used for?

Comparative gene analysis is used to identify similarities and differences in gene sequences across different species, which can provide insights into evolutionary relationships and functional Biology. By comparing genes, researchers can uncover conserved sequences that may indicate essential biological functions, as well as variations that could be linked to specific traits or diseases. This approach is crucial in fields like evolutionary biology, genetics, and medicine, aiding in the understanding of gene function and the development of targeted therapies.
