WebFeb 8, 2024 · Salmonid fish underwent a whole-genome duplication ∼100 million years ago, and presently about 50% of the retained gene duplicates have diverged regulation (Lien et al. 2016). In a recent study (Gillard et al. 2024), we used a comparative phylogenetic approach to explore the impact of WGD on adaptive evolution of gene expression in the … WebThe inheritance of duplicate genes at the same locus may be the result of a population balancing selection process, which, in theory, provides a survival advantage to heterozygotes. All HLA molecules can present antigens to T cells, but each HLA molecule binds a different range of antigens.
WebGene duplication is a common occurrence in the evolution of genomes (Ohno, 1970; Ohta, 1994; Van de Peer et al., 2001 ). It is probably the major source of new genes in the course of evolution. It is also a major means by which cooperative protein complexes arise in evolution ( Orgel, 1977; Zhang, 2003 ).
