A Whole-Genome Duplication: Long-Term Evolution in Genes
Long-term gene evolution following whole-genome replication is an area of high scientific interest. A whole-genome Duplication (WGD), in which an organism has its entire genome duplicated and thus doubles the amount of genetic material. These events are believed to be common in evolution. They can be observed in genomes of animals and plants (Kondrashov, 2016; Brunner, 2021). A common assertion about long-term gene evolution after WGD is that there will be more complexity due to the greater number of available genes for selection. Increased complexity may lead to beneficial traits and adaptations for an organism, and even the creation of new species (Brunner. 2021). It is also believed that WGD may lead to the formation of gene families. This can allow for further evolution as members of different gene families can have different roles and functions (Kondrashov, et al. 2016). Cont….
