Gene duplication
Gene duplication is a process where a segment of DNA containing a gene is copied, resulting in two identical gene copies within the genome. This can occur through errors during cell division or other genetic mechanisms. The duplicated gene may then evolve separately, potentially developing new functions or enhancing existing ones. Gene duplication plays a key role in genetic diversity and evolution, allowing organisms to adapt and develop new traits over time. It is a common way for species to generate genetic variation and complexity.
