Gene expression is central to the genotype-phenotype relationship in all organisms, and it
is an important component of the genetic basis for evolutionary change in diverse aspects of …

The search for the alleles that matter, the quantitative trait nucleotides (QTNs) that underlie
heritable variation within populations and divergence among them, is a popular pursuit. But …

A new field of genetic analysis of global gene expression has emerged in recent years, driven
by the realization that traditional techniques of linkage and association analysis can be …

Cryptic genetic variation (CGV) is invisible under normal conditions, but it can fuel evolution
when circumstances change. In theory, CGV can represent a massive cache of adaptive …

Pleiotropy is the well-established phenomenon of a single gene affecting multiple traits. It
has long played a central role in theoretical, experimental, and clinical research in genetics, …

Recombination rate and linkage disequilibrium, the latter a function of population genomic
processes, are the critical parameters for mapping by linkage and association, and their …

Phyllostomidae is a large (> 140 species), diverse clade of Neotropical bats. Different species
in this family feed on blood, insects, vertebrates, nectar, pollen, and fruits. We investigated …

Abstract Changes in gene expression and regulation—due in particular to the evolution of
cis-regulatory DNA sequences—may underlie many evolutionary changes in phenotypes, yet …

Background The nematode Caenorhabditis elegans is a major laboratory model in biology.
Only ten Caenorhabditis species were available in culture at the onset of this study. Many of …

Natural selection is expected to eliminate genetic incompatibilities from interbreeding
populations. We have discovered a globally distributed incompatibility in the primarily selfing …
