Journal ArticleDOI
Developmental system drift and flexibility in evolutionary trajectories
TL;DR: Current data on the population genetics and molecular mechanisms of DSD illustrate how the details of developmental processes are constantly changing within evolutionary lineages, indicating that developmental systems may possess a great deal of plasticity in their responses to natural selection.
Journal ArticleDOI
Caenorhabditis briggsae recombinant inbred line genotypes reveal inter-strain incompatibility and the evolution of recombination.
Joseph A. Ross,Daniel C. Koboldt,Julia E. Staisch,Helen M. Chamberlin,Bhagwati P. Gupta,Raymond D. Miller,Scott Everet Baird,Eric S. Haag +7 more
TL;DR: Evidence that the two strains diverged in allopatry, the potential for local adaptation, and the evolution of Dobzhansky-Muller incompatibilities are discussed in relation to surprising mitochondrial genome polymorphism in C. briggsae.
Journal ArticleDOI
Genetic Flexibility in the Convergent Evolution of Hermaphroditism in Caenorhabditis Nematodes
Robin Cook Hill,Carlos Egydio de Carvalho,John Salogiannis,Benjamin Schlager,Benjamin Schlager,Dave Pilgrim,Eric S. Haag +6 more
TL;DR: It is shown that C. briggsae requires neither fem-2 nor fem-3 for hermaphrodite development, and that XO Cb-fem-2/3 animals are transformed into hermAPHrodites, not females as in C. elegans.
Journal ArticleDOI
Insights Into Species Divergence and the Evolution of Hermaphroditism From Fertile Interspecies Hybrids of Caenorhabditis Nematodes
TL;DR: The hybrid genetics of the first Caenorhabditis species pair capable of producing fertile hybrid progeny are described, and the use of backcrosses to render the hybrid genome partial homozygous for C. briggsae alleles did not increase the incidence of selfing or spermatogenesis relative to the F1 generation.
Journal ArticleDOI
Detecting heterozygosity in shotgun genome assemblies: Lessons from obligately outcrossing nematodes.
Antoine Barrière,Shiaw-Pyng Yang,Elizabeth Pekarek,Cristel G. Thomas,Eric S. Haag,Ilya Ruvinsky +5 more
TL;DR: This work demonstrates experimentally that independently assembled sequence variants in C. remanei and C. brenneri genomes are allelic and develops a simple method for quantifying heterozygosity that can be applied to assemblies lacking gene annotations.
