Y chromosomes are genetically degenerate, having lost most of the active genes that were
present in their ancestors. The causes of this degeneration have attracted much attention …

Over the past four decades, the predominant view of molecular evolution saw little
connection between natural selection and genome evolution, assuming that the functionally …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Behaviour often depends on the ability to make categorical judgements about sensory
information acquired over time. Such judgements require a comparison of the evidence …

Heterochromatic repeat-rich regions are often missing from even the best genome
assemblies. Chang and Larracuente designed a de novo assembly strategy to improve the …

Sex chromosomes are derived from ordinary autosomes. The X chromosome is thought to
maintain most of its ancestral genes over evolutionary time, whereas its Y counterpart …

The origins and divergence of Drosophila simulans and close relatives D. mauritiana and D.
sechellia were examined using the patterns of DNA sequence variation found within and …

The paucity of polymorphisms in single-copy genes on the Y chromosome of Drosophila
contrasts with data indicating that this chromosome has polymorphic phenotypic effects on …

The thermal range for viability is quite variable among Drosophila species and it has long
been known that these variations are correlated with geographic distribution: temperate …

Genetic conflicts between sexes and generations provide a foundation for understanding the
functional evolution of sex chromosomes and sexually dimorphic phenotypes. Y …
