Understanding the genetic architecture of speciation is a major goal in evolutionary biology.
Hybrid dysfunction is thought to arise most commonly through negative interactions between …

Methods of transcriptional profiling have made it possible to compare gene expression
between females and males on a genome-wide scale. Such studies have revealed that sex …

Population genetics theory predicts that X (or Z) chromosomes could play disproportionate
roles in speciation and evolutionary divergence, and recent genome-wide analyses have …

A faster rate of adaptive evolution of X‐linked genes compared with autosomal genes can
be caused by the fixation of recessive or partially recessive advantageous mutations, due to …

Males and females often have marked phenotypic differences, and the expression of these
dissimilarities invariably involves sex differences in gene expression. Sex-biased gene …

Sexually dimorphic phenotypes are thought to largely result from sex differences in gene
expression, and genes with sex-biased expression have been well characterized in adults of …

Studies of X chromosome evolution in various organisms have indicated that sex-biased
genes are nonrandomly distributed between the X and autosomes. Here, to extend these …

The elevated rate of evolution for genes on sex chromosomes compared with autosomes
(Fast-X or Fast-Z evolution) can result either from positive selection in the heterogametic sex …

Systematic characterization of ẖybrid i ncompatibility (HI) between related species remains
the key to understanding speciation. The genetic basis of HI has been intensively studied in …

Complete dosage compensation refers to hyperexpression of the entire X or Z chromosome
in organisms with heterogametic sex chromosomes (XY male or ZW female) in order to …
