متن کاملReconstruction of Ancestral Genome Subject to Whole Genome Duplication, Speciation, Rearrangement and Loss
Whole genome duplication (WGD) is a rare evolutionary event that has played a dramatic role in the diversification of most eucaryotic lineages. Given a set of species known to have evolved from a common ancestor through one or many rounds of WGD together with a set of genome rearrangements, and a phylogenetic tree for these species, the goal is to infer the pre-duplicated ancestral genomes. We ...
متن کاملGenome duplication, divergent resolution and speciation.
What are the evolutionary consequences of gene duplication? One answer is speciation, according to a model initially called Reciprocal Silencing and recently expanded and renamed Divergent Resolution. This model shows how the loss of different copies of a duplicated gene in allopatric populations (divergent resolution) can promote speciation by genetically isolating these populations should the...
متن کاملThe limited contribution of reciprocal gene loss to increased speciation rates following whole-genome duplication.
Hybrid incompatibilities contribute to reproductive isolation between species, allowing them to follow independent evolutionary trajectories. Since hybrid incompatibilities are by definition deleterious, they cannot be selected for directly and must arise as a by-product of evolutionary divergence. Divergent resolution of duplicate genes, a special case of Dobzhansky-Muller incompatibilities, i...
