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 …

Progress on understanding how genome structure evolves is accelerating with the arrival of
new genomic, comparative, and theoretical approaches. This article reviews progress in …

Insects harbor a tremendous diversity of sex determining mechanisms both within and
between groups. For example, in some orders such as Hymenoptera, all members are …

The association of chromosome rearrangements (CRs) with speciation is well established,
and there is a long history of theory and evidence relating to “chromosomal speciation.” …

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 …

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 …

Fishes exhibit the greatest diversity of species among vertebrates, offering a number of
relevant models for genetic and evolutionary studies. The investigation of sex chromosome …

The reconstruction of the evolutionary dynamics of karyotypes and sex determining systems
in squamate reptiles is precluded by the lack of data in many groups including most …

Whole-genome duplication (WGD) can have large impacts on genome evolution, and much
remains unknown about these impacts. This includes the mechanisms of coping with a …

The evolution of genes related to sex and reproduction in fish shows high plasticity and, to
date, the sex determination system has only been identified in a few species. Solea …
