Uncovering the genetic and evolutionary basis of local adaptation is a major focus of
evolutionary biology. The recent development of cost-effective methods for obtaining high …

Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex
chromosome systems, making it possible to empirically test the rich body of evolutionary …

Although sex is a fundamental component of eukaryotic reproduction, the genetic systems
that control sex determination are highly variable. In many organisms the presence of sex …

Motivation Linkage disequilibrium (LD) measures the correlation between genetic loci and is
highly informative for association map** and population genetics. As many studies rely on …

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 …

The profound and pervasive differences in gene expression observed between males and
females, and the unique evolutionary properties of these genes in many species, have led to …

Bird sex chromosomes play a unique role in sex-determination, and affect the sexual
morphology and behavior of bird species. Core waterbirds, a major clade of birds, share the …

Abstract Theory and empirical patterns suggest a disproportionate role for sex chromosomes
in evolution and speciation. Focusing on ZW sex determination (females ZW, males ZZ; the …

The ubiquity of the “two rules of speciation”—Haldane's rule and the large X‐effect—implies
a general, special role for sex chromosomes in the evolution of intrinsic postzygotic …

Sex chromosomes evolve once recombination is halted between a homologous pair of
chromosomes. The dominant model of sex chromosome evolution posits that recombination …
