Recombination is critical both for accelerating adaptation and purging deleterious mutations.
Chromosomal inversions can act as recombination modifiers that suppress local …

Population genetic theory suggests that mating designs employing one or more generations
of sib-crossing or selfing prior to backcrossing are more effective than backcrossing alone …

Genetic analyses of reproductive barriers represent one of the few methods by which
theories of speciation can be tested. However, genetic study is often restricted to model …

For populations to maintain optimal fitness, harmful mutations must be efficiently purged
from the genome. Yet, under circumstances that diminish the effectiveness of natural …

Understanding the genetic mechanisms of speciation and basis of species differences is
among the most important challenges in evolutionary biology. Two questions of particular …

Chromosomal inversions are increasingly found to differentiate locally adapted populations.
This adaptive role is predictable because reduced recombination protects allelic …

Hybridization is a natural phenomenon that has been linked in several organismal groups to
transposable element derepression and copy number amplification. A noteworthy example …

Plant species may remain morphologically distinct despite gene exchange with congeners,
yet little is known about the genomewide pattern of introgression among species. Here we …

The combination of large-scale population genomic analyses and trait-based mapping
approaches has the potential to provide novel insights into the evolutionary history and …

Both models and case studies suggest that chromosomal inversions can facilitate adaptation
and speciation in the presence of gene flow by suppressing recombination between locally …
