Question

Quizplus · Accepted Answer

Gene duplication is the process where a gene is duplicated in the genome, resulting in multiple copies of the same gene. This can occur through various mechanisms such as unequal crossing over during meiosis, retrotransposition, or chromosomal duplication events. The duplicated genes can then undergo divergence through mutation and natural selection, leading to the formation of gene families with related but distinct functions.
