Question

Duplication followed by evolutionary divergence is the major mechanism of introducing new genes into eukaryotic genomes. This process involves a duplication of a gene or genomic region, followed by mutations and evolutionary divergence of one or both copies, resulting in the emergence of new genes and functions. Unequal crossing over at microsatellite repeats can also lead to duplications, but it is not a major mechanism. Pseudogene creation and restoration do not introduce new functional genes, and transfer from viruses is relatively rare and more common in prokaryotes.
