• TITLE: Reproductive isolation in the Elegans-Group of Caenorhabditis

  AUTHORS: Scott Everet Baird, Sara R. Seibert

  KEYWORDS: Caenorhabditis; Pre-Mating Isolation; Assortative Fertilization; Post-Zygotic Isolation

  JOURNAL NAME: Natural Science, Vol.5 No.4A, April 30, 2013

  ABSTRACT: Reproductive isolation is the basis of the Biological Species Definition and can be a driving force of speciation. Theoretical studies have provided models of how reproductive isolation can arise within individual species. Genetic tests of these models are limited to populations in which reproductive isolation is present but not complete. Here, reproductive isolation in the Elgans-Group of the nematode genus Caenorhabditis is reviewed. Pre-mating barriers, assortative fertilization and post-zygotic barriers all have been observed in this clade. In some combinations of species, fertile F1 hybrids can be obtained. Therefore, the Elegans-Group of Caenorhabditis is poised to become an important experimental system for the study of reproductive isolation.
