- multiple hooks
Male animals exhibit multiple copulatory hooks. In wild type C. elegans males, a single hook is normally present.
- aberrant posteriorly-directed neurite
Any neurite that is extended towards the posterior of the animal from neurons that in wild-type animals make only anterior projections (e.g. D-type neurons in C. elegans).
- systemic RNAi variant
Animals are defective for RNAi introduced by environmental means such as in the cases of RNAi triggered by soaking or feeding.
- persistent primordial germ cell lobes
Animals exhibit persistent cellular lobes of the primordial germ cells Z2 and/or Z3 at the L1 larval stage or later, in contrast to wild type animals
- swimming induced paralysis
Animals become paralyzed after a measured amount of time swimming. In C. elegans, more then 80 percent of wild-type animals continue swimming vigorously in liquid even after 30 minutes.
- 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.
- osmolarity modulated swimming variant
The swimming behavior of animals are influenced or modulate by the osmolarity of the swimming buffer. The swimming of wild-type C. elegans animals are not affected by the osmolarity of the swimming liquid.
- dominant negative enzyme
Any variation within an enzyme that causes it to act antagonistically towards the wild-type enzymatic product. These mutations usually result in an altered molecular function (often inactive) and are characterized by a dominant or semi-dominant phenotype.
- RNAi resistant
Animals show reduced susceptibility to gene silencing triggered by double stranded RNA (RNAi), compared to control.
