About Caenorhabditis nigoni
Caenorhabditis nigoni is a male-female species in the Elegans group of the Caenorhabditis genus, first identified and described as "Caenorhabditis species 9" or "C. sp. 9" before being renamed as "Caenorhabditis nigoni". The specific epithet is a tribute to Victor Nigon who first studied Caenorhabditis elegans in the laboratory with Ellsworth Dougherty in the 1940s. \n \n_C. nigoni_ is noteworthy because it is very closely related to the hermaphroditic species C. briggsae. Despite substantial differences between C. nigoni and C. briggsae in their modes of sexual reproduction, their genome sizes, and their protein-coding gene counts, the two species can interbreed to produce not merely viable male and female hybrid offspring, but partially fertile female hybrid offspring.
