Selection and gene duplication: a view from the genome
A Wagner - Genome biology, 2002 - Springer
Immediately after a gene duplication event, the duplicate genes have redundant functions. Is
natural selection therefore completely relaxed after duplication? Does one gene evolve …

Copy-number changes in evolution: rates, fitness effects and adaptive significance
V Katju, U Bergthorsson - Frontiers in genetics, 2013 - frontiersin.org
Gene copy-number differences due to gene duplications and deletions are rampant in
natural populations and play a crucial role in the evolution of genome complexity. Per-locus …

Genomic expression dominance in allopolyploids
Background Allopolyploid speciation requires rapid evolutionary reconciliation of two
diverged genomes and gene regulatory networks. Here we describe global patterns of gene …

Many gene and domain families have convergent fates following independent whole-genome duplication events in Arabidopsis, Oryza, Saccharomyces and …
Genome duplication is potentially a good source of new genes, but such genes take time to
evolve. We have found a group of 'duplication-resistant'genes, which have undergone …

Extensive chromosomal variation in a recently formed natural allopolyploid species, Tragopogon miscellus (Asteraceae)
M Chester, JP Gallagher… - Proceedings of the …, 2012 - National Acad Sciences
Polyploidy, or whole genome duplication, has played a major role in the evolution of many
eukaryotic lineages. Although the prevalence of polyploidy in plants is well documented, the …

The evolution of haploidy and diploidy
SP Otto, AC Gerstein - Current Biology, 2008 - cell.com
Tremendous diversity exists among organisms with respect to their ploidy level, defined as
the number of sets of homologous chromosomes per cell. As differences in ploidy represent …
