WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
WBPhenotype:0000081
|
L1 arrest
|
The developmental program of the animals does not continue past the first larval stage (L1). |
WBPhenotype:0000050
|
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. |
WBPhenotype:0000070
|
male tail morphology variant
|
Animals exhibit variations in the structure or organization of the somatic reproductive components of the posterior segment of the male from that observed in control males. In C. elegans, this region of the male includes the terminal canals of the reproductive tract, the digestive tract, and spicule channels along with the male specific sensilla (ray, post-cloacal, hook and spicule) and extends to the tip of the acellular fan. |
WBPhenotype:0000634
|
pharyngeal pumping variant
|
Any variation in the contraction and relaxation movements of the pharyngeal muscle that mediate feeding in nematodes compared to control. |
WBPhenotype:0000054
|
larval lethal
|
The animal dies at any time between hatching and onset to adulthood. |
WBPhenotype:0000690
|
gonad migration variant
|
Variations in the gross movement of the whole structure of the gonad along the body wall, behind the gonadal leader cell and away from the developing vulva compared to control (Wormatlas). |
WBPhenotype:0000709
|
pharyngeal morphology variant
|
Variations in the form or composition of the mouthparts at the anterior end of the digestive tract which contain a series of radial muscles, related neurons and epithelial cells, and several gland cells which may aid in digestion compared to control (Wormatlas). |
WBPhenotype:0000368
|
one point five fold arrest emb
|
Cessation of development that normally occurs in C. elegans 420-460 min after the first embryonic cleavage at 20C, the stage between the comma and 2-fold embryo. |
