Question

Quizplus · Accepted Answer

Duplication and divergence, or the process of creating new genes through gene duplication followed by mutation and differentiation in function, is the major mechanism of introducing new genes into the eukaryotic genome. Lateral gene transfer, common in prokaryotes, is rare in eukaryotes. Pseudogene creation and restoration are not processes that introduce new genes into the genome, and unequal crossing over at microsatellite repeats can cause genetic disorders but does not introduce entirely new genes.
