dauer axial ratio variant

Any variation in the ratio of the body length to body width in a dauer stage animal, compared to control. Long thin animals will have a high axial ratio.

temperature learning variant

Wild-type animals will exhibit an altered temperature preference based on food/temperature conditioning. Temperature learning variants do not exhibit altered responses to temperature after conditioning compared to control animals.

gustatory aversive learning abnormal

Variations in the aversion of animals to substances sensed by gustation (taste) previously associated with an aversive stimuli during a gustation training protocol, compared to control. For example, C. elegans animals can be trained to associate the taste of a substance (e.g. sodium chloride, normally an attractant) to an aversive stimuli (e.g. starvation) so that trained worms will avoid the substance in the absence of the aversive stimuli. Animals with this phenotype will not exhibit the same aversion to the substance as compared to control animals.

spicule insertion defective

Males exhibit defects in the insertion of the male copulatory spicules into the mating partner. In C. elegan spicule insertion behavior initiates when the male cloaca contacts the vulva. During most mating encounters, the spicule tips will prod the vulva continuously until they partially penetrate, which then causes the protractors to contract completely so that the spicules extend through the vulva.

gustatory learning abnormal

Variations in the behavioral plasticity induced by the integration of two sensory signals (one of which is gustation (taste)) compared to control. For example, C. elegans animals can be trained to associate the taste of a substance (e.g. sodium chloride, normally an attractant) to an aversive stimuli (e.g. starvation) so that trained worms will avoid the substance in the absence of the aversive stimuli. Animals with this phenotype have an abnormal response to the trained stimuli compared to controls.
