excess intestinal cells

Animals contain an excess number of intestinal cells compared to control. In C. elegans, intestinal cells are derived from E-blastomere. The overproduction of intestinal tissues is a result of other blastomeres adopting an E-like fate or excess cell proliferation in the E lineage.

no Intestine

Embryos fail to generate cells that exhibit intestinal specification. In C. elegans, the E blastomere is the precursor of all the intestinal cells.

population fitness phenotype

Populations exhibit variations in the ability to survive, grow and reproduce, thus affecting the contribution to the gene pool over generations compared to control populations. In C. elegans the fitness of a population can by assessed by measuring the rate at which E. coli is consumed.

E lineage variant

The descendants of the E blastomere exhibit altered developmental programs compared to their counterparts in control animals.

octanol chemotaxis variant

Any variation in the directed movement of a worm in response to a specific concentration gradient of octanol. In C. elegans, octanol is typically a repellant.

nonanone chemotaxis variant

Any variation in the directed movement of a worm in response to a specific concentration gradient of nonanone. In C. elegans, nonanone is typically a repellant.

quinine chemotaxis variant

Any variation in the directed movement of a worm in response to a specific concentration gradient of the bitter tastant quinine, a water soluble molecule. In C. elegans, quinine is typically a repellant.

garlic chemotaxis variant

Any variation in the directed movement of a worm in response to a specific concentration gradient of garlic compared to control. In C. elegans, garlic is typically a repellant.

curly

Animals exhibit a greater number of bends in their body compared to control. C. elegans posture assumes more than a single sine wave.

vulvaless

No vulval tissue is produced. In C. elegans, this is usually a result of all six vulval precursor cells adopting a tertiary fate.
