Abstract
Two strains (Bergerac and Bristol) of the nematode Caenorhabditis elegans, with different temperature tolerances, were reared axenically at 23 degrees to 25 degrees C. The Bergerac strain is heat sensitive (that is, it is sterile at maturity), whereas the Bristol strain is heat resistant (that is, it matures and reproduces normally). Hybrid hermaphrodites (F(1)), produced by crossing Bristol males and Bergerac hermaphrodites, are heat tolerant. Heat sensitivity segregates as a simple Mendelian recessive in the F(2) and F(3) generations.Entities:
