Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex
chromosome systems, making it possible to empirically test the rich body of evolutionary …

Many species groups, including mammals and many insects, determine sex using
heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila …

The Genome 10K Project was established in 2009 by a consortium of biologists and
genome scientists determined to facilitate the sequencing and analysis of the complete …

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

Although sex is a fundamental component of eukaryotic reproduction, the genetic systems
that control sex determination are highly variable. In many organisms the presence of sex …

Animal sex chromosomes typically carry the upstream sex-determining gene that triggers
testis or ovary development and, in some species, are regulated by global dosage …

Sex chromosomes have evolved many times in animals and studying these replicate
evolutionary “experiments” can help broaden our understanding of the general forces …

Here we use a chromosome-level genome assembly of a prairie rattlesnake (Crotalus
viridis), together with Hi-C, RNA-seq, and whole-genome resequencing data, to study key …

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 …
