In species with genetic sex-determination, the chromosomes carrying the sex-determining
genes have often evolved non-recombining regions and subsequently evolved the full set of …

Plant sex chromosomes can be vastly different from those of the few historical animal model
organisms from which most of our understanding of sex chromosome evolution is derived …

Variation in social behaviour is common, yet little is known about the genetic architectures
underpinning its evolution. A rare exception is in the fire ant Solenopsis invicta: Alternative …

Genome evolution is predicted to be rapid following the establishment of new (neo) sex
chromosomes, but it is not known if neo-sex chromosome evolution plays an important role …

Sex chromosomes can evolve when recombination is halted between a pair of
chromosomes, and this can lead to degeneration of the sex-limited chromosome. In the early …

We report the discovery of a neo-sex chromosome in the monarch butterfly, Danaus
plexippus, and several of its close relatives. Z-linked scaffolds in the D. plexippus genome …

Sex chromosomes are unique regions of the genome, with a host of properties that
distinguish them from autosomes and from each other. Although there is extensive theory …

Plants have evolved a diverse array of strategies for sexual reproduction, particularly
through the modification of male and female organs at distinct points in development. The …

Key message This review gives a comprehensive overview on the genomics of sex
determination in dioecious woody plants and plants with a tree-like habitus, in particular …

X and Y chromosomes differ in effective population size (Ne), rates of recombination, and
exposure to natural selection, all of which can affect patterns of genetic diversity. On Y …
