Sexual dimorphism is common throughout the animal kingdom. However, a molecular
understanding of how sex-specific traits develop and evolve has been elusive. Recently …

The Caenorhabditis elegans germ line provides an exceptional model for analysis of the
molecular controls governing stem cell maintenance, the cell cycle transition from mitosis to …

The ability to identify genetic markers in nonmodel systems has allowed geneticists to
construct linkage maps for a diversity of species, and the sex-determining locus is often …

Experiences have been shown to modulate behavior and physiology of future generations in
some contexts, but there is limited evidence for inheritance of associative memory in …

Sex determination mechanisms evolve surprisingly rapidly, yet little is known in the large
nematode phylum other than for Caenorhabditis elegans, which relies on chromosomal XX …

The architecture of both phenotypic variation and reproductive isolation are important
problems in evolutionary genetics. The nematode genus Caenorhabditis includes both …

The transition of the sexual mode occurs widely in animal evolution. In Caenorhabditis
nematodes, androdioecy, a sexual polymorphism composed of males and hermaphrodites …

The self-fertile hermaphrodites of C. elegans and C. briggsae evolved from female ancestors
by acquiring limited spermatogenesis. Initiation of C. elegans hermaphrodite …

The ability of ribosomes to translate mRNAs into proteins is the basis of all life. While
ribosomes are essential for cell viability, reduction in levels of ribosomes can affect cell fate …

Molecular genetic analysis of phenotypic variation has revealed many examples of
evolutionary change in the developmental pathways that control plant and animal …
