Aquaculture is one of the most efficient modes of animal protein production and plays an
important role in global food security. Aquaculture animals exhibit extraordinarily diverse …

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 …

The canonical model of sex-chromosome evolution predicts that, as recombination is
suppressed along sex chromosomes, gametologs will progressively differentiate, eventually …

With more than 70,000 living species, vertebrates have a huge impact on the field of biology
and research, including karyotype evolution. One prominent aspect of many vertebrate …

Is sex a product of genes, the environment, or both? In this review, we describe the diversity
of sex-determining mechanisms in reptiles, with a focus on systems that display gene …

Studies of reptile (nonavian reptiles) chromosomes began well over a century ago (1897)
with the initial report on the description of sand lizard (Lacerta agilis) chromosomes. Since …

How consistent are the evolutionary trajectories of sex chromosomes shortly after they form?
Insights into the evolution of recombination, differentiation, and degeneration can be …

Sex chromosome evolution remains an evolutionary puzzle despite its importance in
understanding sexual development and genome evolution. The seemingly random …

The diversity of sex chromosomes among amniotes is the product of independent evolution
of different systems in different lineages, defined by novel sex-determining genes …

Sex chromosome dosage compensation (SCDC) overcomes gene-dose imbalances that
disturb transcriptional networks, as when ZW females or XY males are hemizygous for Z/X …
