- plugged excretory pore
Males receive copulatory plugs from other males, deposited on their excretory pores. This phenotype is polymorphic among C. elegans strains and also in C. briggsae.
- sodium acetate chemotaxis defective
Failure in directed movement in response to sodium acetate. In C. elegans, sodium acetate is an attractant. Sodium acetate has also subsequently been used to assay for Na+ attraction in C. elegans.
- ammonium chloride chemotaxis defective
Failure in directed movement in response to ammonium chloride compared to control. In C. elegans, NH4Cl is an attractant. NH4Cl has also subsequently been used to assay for Cl- attraction in C. elegans.
- embryonic lethal
Animals die during embryonic development. In C. elegans, often assayed as refractile eggs that fail to hatch; when applied to large-scale RNAi screens in C. elegans, more than 10% of embryos die.
- temperature induced dauer formation variant
Animals exhibit variations in the entry into the dauer stage when exposed to temperatures that induce dauer formation in control animals. In C. elegans, many Daf-c animals enter dauer at 25C, whereas Hid animals enter dauer at 27C.
- C lineage variant
The descendants of the C blastomere exhibit altered developmental programs compared to their counterparts in control animals.
- stuffed pharynx
Pharynx becomes clogged with food. In C. elegans, this is often a result of pharyngeal pumping defects.
- nonanone chemotaxis defective
Failure to execute the characteristic response to nonanone compared to control. In C. elegans, nonanone is a repellant.
- multiple hooks
Male animals exhibit multiple copulatory hooks. In wild type C. elegans males, a single hook is normally present.
