They arise through mechanisms like unequal crossing over, retroposition, or whole-genome duplication (WGD). Once a gene is duplicated, one copy can conserve its original role, while the other diverges; fueling new functions, adaptations, or even nonfunctionalization (pseudogenes). πΉ The evolutionary fates of gene duplications includes: Subfunctionalization: split ancestral functions across duplicates. Neofunctionalization: gain of new roles, which is vital for innovation. Pseudogenization: loss of function. A classic case is the globin gene family: duplications enabled the evolution of h...
