Evolution by gene and genome duplication

WebJun 26, 2024 · Whole-genome duplication (WGD) events are pervasive in eukaryotes, shaping the genomes of simple single-celled organisms, such as yeast, as well as those of more complex metazoans, including humans. Most duplicated genes are eliminated after WGD because one copy accumulates deleterious mutations, leading to its loss.
