Cytonuclear Genetic Incompatibilities in Plant Speciation [PDF]
Due to the endosymbiotic origin of organelles, a pattern of coevolution and coadaptation between organellar and nuclear genomes is required for proper cell function.

Genetic Links between Recombination and Speciation. [PDF]
Meiosis distinguishes cells in the germ line from their somatic counterparts. Part of meiosis involves a bizarre series of events in which cells deliberately damage their DNA and then repair it. Of the many double-strand breaks that are generated, a minority are resolved as reciprocal exchanges between homologous chromosomes [1].

Mating system and speciation I: Accumulation of genetic incompatibilities in allopatry.
Self-fertilisation is widespread among hermaphroditic species across the tree of life. Selfing has many consequences on the genetic diversity and the evolutionary dynamics of populations, which may in turn affect macroevolutionary processes such as ...

Soil bacteria respond rapidly to changes in new environmental conditions. For adaptation to the new environment, they could mutate their genome, which impacts the alternation of the functional and regulatory landscape.

Genetics and ecological speciation [PDF]
Species originate frequently by natural selection. A general mechanism by which this occurs is ecological speciation, defined as the evolution of reproductive isolation between populations as a result of ecologically-based divergent natural selection. The alternative mechanism is mutation-order speciation in which populations fix different mutations as

Incipient speciation between host-plant strains in the fall armyworm
Background Recent advancement in speciation biology proposes that genetic differentiation across the whole genome (genomic differentiation, GD) may occur at the beginning of a speciation process and that GD itself may accelerate the rate of speciation ...

Background Understanding how species diversify is a long-standing question in biology. The allopatric speciation model is a classic hypothesis to explain the speciation process. This model supposes that there is no gene flow during the divergence process

The genetic basis of speciation in free‐spawning marine invertebrates is poorly understood. Although gene copy number variations (GCNVs) and nucleotide variations possibly trigger the speciation of these organisms, empirical evidence for such a ...

Ecologically divergent selection can lead to the evolution of reproductive isolation through the process of ecological speciation, but the balance of responsible evolutionary forces is often obscured by an inadequate assessment of demographic history and

The evolutionary genetics of speciation [PDF]
The last decade has brought renewed interest in the genetics of speciation, yielding a number of new models and empirical results. Defining speciation as ‘the origin of reproductive isolation between two taxa’, we review recent theoretical studies and relevant data, emphasizing the regular patterns seen among genetic analyses.
