The genetic architecture of adaptive traits is of key importance to predict evolutionary
responses. Most adaptive traits are polygenic—ie, result from selection on a large number of …

Background Heteromorphic sex chromosomes have evolved repeatedly across diverse
species. Suppression of recombination between X and Y chromosomes leads to …

It is widely accepted that the genomic distribution of transposable elements (TEs) mainly
reflects the outcome of purifying selection and insertion bias. Nevertheless, the relative …

Heterochromatic repeat-rich regions are often missing from even the best genome
assemblies. Chang and Larracuente designed a de novo assembly strategy to improve the …

The rapid evolution of repetitive DNA sequences, including satellite DNA, tandem
duplications, and transposable elements, underlies phenotypic evolution and contributes to …

Intralocus sexually antagonistic selection occurs when an allele is beneficial to one sex but
detrimental to the other. This form of selection is thought to be key to the evolution of sex …

Y chromosomes across diverse species convergently evolve a gene-poor, heterochromatic
organization enriched for duplicated genes, LTR retrotransposons, and satellite DNA …

Loss of recombination between sex chromosomes often depletes Y chromosomes of
functional content and genetic variation, which might limit their potential to generate …

Sex chromosomes or sex-determining regions (SDR) have been discovered in many
dioecious plant species, including the iconic 'living fossil'Ginkgo biloba, though the location …

Background Understanding the genetic architecture of temperature adaptation is key for
characterizing and predicting the effect of climate change on natural populations. One …
