The human Y chromosome is intriguing not only because it harbours the master-switch gene
that determines gender but also because of its unusual evolutionary history. The Y …

Understanding phylogenetic relationships among taxa is key to designing and implementing
comparative analyses. The genus Drosophila, which contains over 1600 species, is one of …

Reconstruction of target genomes from sequence data produced by instruments that are
agnostic as to the species-of-origin may be confounded by contaminant DNA. Whether …

Fruit flies of the genus Drosophila have been an attractive and effective genetic model
organism since Thomas Hunt Morgan and colleagues made seminal discoveries with them …

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

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 …

Herbivory is a key innovation in insects, yet has only evolved in one-third of living orders.
The evolution of herbivory likely involves major behavioral changes mediated by remodeling …

B chromosomes (Bs) are dispensable components of the genome exhibiting non-Mendelian
inheritance and have been widely reported on over several thousand eukaryotes, but still …

Sex chromosomes are generally derived from a pair of classical type-A chromosomes, and
relatively few alternative models have been proposed up to now. 1, 2 B chromosomes (Bs) …

Many animal species employ sperm nuclear basic proteins (SNBPs) or protamines to
package sperm genomes tightly. SNBPs vary across animal lineages and evolve rapidly in …
