Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

Speciation with gene flow is greatly facilitated when traits subject to divergent selection also
contribute to non-random mating. Such traits have been called 'magic traits', which could be …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Levels of genetic differentiation between populations can be highly variable across the
genome, with divergent selection contributing to such heterogeneous genomic divergence …

The suggestion that chromosomal rearrangements play a role in speciation resulted from the
observation that heterokaryotypes are often infertile. However, the first chromosomal …

Over the past decade, many studies documented high genetic divergence between closely
related species in genomic regions experiencing restricted recombination in hybrids, such …

Speciation with gene flow is expected to generate a heterogeneous pattern of genomic
differentiation. The few genes under or physically linked to loci experiencing strong …

Genes under divergent selection flow less readily between populations than other loci. This
observation has led to verbal “divergence hitchhiking” models of speciation in which …

Understanding the genetic basis of reproductive isolation is a central issue in the study of
speciation. Structural variants (SVs); that is, structural changes in DNA, including inversions …

Abstract Background Single nucleotide polymorphisms (SNPs) are ideally suited for the
construction of high-resolution genetic maps, studying population evolutionary history and …
