The Long-Term Evolution of Genes Following a Whole-Genome Duplication

The long-term evolution of genes following a whole-genome duplication is a topic of great interest in the scientific community. Whole-genome duplication (WGD) is an event in which an organism’s entire genome is duplicated, thus doubling the genetic material. It is believed to occur periodically in the evolution of certain organisms, and the effects of this event can be seen in the genomes of organisms such as plants and animals (Kondrashov et al., 2016; Brunner et al., 2021). The most common statement about the long-term evolution of genes following WGD is that it leads to increased complexity, due to the increased number of genes available for selection (Kondrashov et al., 2016). This increased complexity can result in new traits and adaptations that are beneficial to the organism and can lead to the emergence of new species (Brunner et al., 2021). Additionally, it is believed that WGD can lead to the emergence of gene families, which can lead to further evolution, as different members of a gene family may have different functions and roles (Kondrashov et al., 2016).
