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 …

Sex chromosomes are widespread in species with separate sexes. They have evolved many
times independently and display a truly remarkable diversity. New sequencing technologies …

Many animals with genetic sex determination harbor heteromorphic sex chromosomes,
where the heterogametic sex has half the gene dose of the homogametic sex. This …

Males are XY and females are XX in most mammalian species. Other species such as birds
have a different sex chromosome make-up: ZZ in males and ZW in females. In both types of …

In many multicellular eukaryotes, heteromorphic sex chromosomes are responsible for
determining the sexual characteristics and reproductive functions of individuals. Sex …

Abstract The eastern North American monarch butterfly, Danaus plexippus, is an emerging
model system to study the neural, molecular, and genetic basis of animal long-distance …

Mechanisms of sex chromosome dosage compensation (SCDC) differ strikingly among
animals. In Drosophila flies, chromosome-wide transcription is doubled from the single X …

We report a draft assembly of the genome of Hi5 cells from the lepidopteran insect pest,
Trichoplusia ni, assigning 90.6% of bases to one of 28 chromosomes and predicting 14,037 …

Sex determination in varanids, Gila monsters, beaded lizards, and other anguimorphan
lizards is still poorly understood. Sex chromosomes were reported only in a few species …

Plants and insects often use the same compounds for chemical communication, but not
much is known about the genetics of convergent evolution of chemical signals. The terpene …
