|a Two new "dumpy" mutants (Hbdpy-2 and Hbdpy-3) of Heterorhabditis bacteriophora were induced and characterized. Mutants (hermaphrodites and males) that hatched from eggs were shorter and wider than the wild-type strain. This phenotype was not discernible in young animals until 24 hours after hatching from eggs or in mutants that developed from infective juveniles. Scanning electron microscopy revealed that the tails of the two mutants are much more slender than in the wild-type. In addition, the vulva of Hbdpy-3 nematodes appeared to be sunken; that of Hbdpy-2 animals was protruding, like in the wild-type. Upon self fertilization, individual Hbdpy-3 hermaphrodites produced fewer progeny than the wild-type. Crosses between virgin Hbdpy-2 and Hbdpy-3 hermaphrodites and wild-type males indicated that the two mutations are recessive. Complementation tests indicated that Hbdpy-1, Hbdpy-2, and Hbdpy-3 affect different genes. The ratio (1.03:1) of wild-type to dumpy phenotype among the F progeny of self-fertilizing heterozygotes suggested linkage among the three genes. The genetic map distance was estimated only between Hbdpy-1 and Hbdpy-2 genes, approximately 29 map units
