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 …

Molecular population genetics aims to explain genetic variation and molecular evolution
from population genetics principles. The field was born 50 years ago with the first measures …

Annotating coding genes and inferring orthologs are two classical challenges in genomics
and evolutionary biology that have traditionally been approached separately, limiting …

Hybridization between humans and Neanderthals has resulted in a low level of Neanderthal
ancestry scattered across the genomes of many modern-day humans. After hybridization, on …

We review knowledge about the roles of sex chromosomes in vertebrate hybridization and
speciation, exploring a gradient of divergences with increasing reproductive isolation …

Sexual dimorphism is one of the most prevalent, and often the most extreme, examples of
phenotypic variation within species, and arises primarily from genomic variation that is …

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 …

Genetic degeneration is an extraordinary feature of sex chromosomes, with the loss of
functions of Y-linked genes in species with XY systems, and W-linked genes in ZW systems …
