Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

Patterns of variation and evolution at a given site in a genome can be strongly influenced by
the effects of selection at genetically linked sites. In particular, the recombination rates of …

Speciation is a continuous process during which genetic changes gradually accumulate in
the genomes of diverging species. Recent studies have documented highly heterogeneous …

One of the most striking patterns of genome structure is the tight, typically negative,
association between transposable elements (TEs) and meiotic recombination rates. While …

We describe the astonishing changes and progress that have occurred in the field of
population genetics over the past 50 years, slightly longer than the time since the first …

Mutation is fundamental to evolution, because it generates the genetic variation on which
selection can act. In nature, genetic changes often increase the mutation rate in systems that …

In many species, the Y (or W) sex chromosome is degenerate. Current theory proposes that
this degeneration follows the arrest of recombination and results from the accumulation of …

Recombination rate is heterogeneous across the genome of various species and so are
genetic diversity and differentiation as a consequence of linked selection. However, we still …

Understanding the evolutionary mechanisms generating parallel genomic divergence
patterns among replicate ecotype pairs remains an important challenge in speciation …

The consequences of selection at linked sites are multiple and widespread across the
genomes of most species. Here, I first review the main concepts behind models of selection …
