Inference of Ancient Whole-Genome Duplications and the Evolution of Gene Duplication and Loss Rates [PDF]
Abstract Gene tree–species tree reconciliation methods have been employed for studying ancient whole-genome duplication (WGD) events across the eukaryotic tree of life. Most approaches have relied on using maximum likelihood trees and the maximum parsimony reconciliation thereof to count duplication events on specific branches of ...

Background Multiple processes impact the probability of retention of individual genes following whole genome duplication (WGD) events. In analyzing two consecutive whole genome duplication events that occurred in the lineage leading to Atlantic salmon, a

Whole genome duplications and the diversification of the Globin-X genes of vertebrates [PDF]
Abstract The globin superfamily of vertebrate genes is a textbook example of how the interplay between local gene duplications, whole-genome duplications, and regulatory changes can facilitate the evolution of novel protein functions.

Beyond the Whole-Genome Duplication: Phylogenetic Evidence for an Ancient Interspecies Hybridization in the Baker's Yeast Lineage. [PDF]
Whole-genome duplications have shaped the genomes of several vertebrate, plant, and fungal lineages. Earlier studies have focused on establishing when these events occurred and on elucidating their functional and evolutionary consequences, but we still ...

The shape of human gene family phylogenies [PDF]
Background: The shape of phylogenetic trees has been used to make inferences about the evolutionary process by comparing the shapes of actual phylogenies with those expected under simple models of the speciation process. Previous studies have focused

Subfunctionalization versus neofunctionalization after whole-genome duplication [PDF]
The question of what is the predominant evolutionary fate of genes after duplication events has been hotly debated for decades 1,2 . Two recently published articles in Nature (Lien et al . 3 ) and Nature Genetics (Braasch

Whole genome duplication and transposable element proliferation drive genome expansion in Corydoradinae catfishes [PDF]
Genome size varies significantly across eukaryotic taxa and the largest changes are typically driven by macro-mutations such as whole genome duplications (WGDs) and proliferation of repetitive elements.

Whole Genome Duplications and Contracted Breakpoint Graphs
The genome halving problem, motivated by the whole genome duplication events in molecular evolution, was solved by El-Mabrouk and Sankoff in the pioneering paper [SIAM J. Comput., 32 (2003), pp. 754-792]. The El-Mabrouk-Sankoff algorithm is rather complex, inspiring a quest for a simpler solution.
