|
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:0000638
|
molt defect
|
Animals exhibit defects in the process of periodic shedding, of part or all of its cuticle, during cuticle replacement that punctuates each larval stage. |
WBPhenotype:0000645
|
roller
|
The body of the animal rotates around its long axis as the animal moves, causing the animal to move in a circular pattern. In liquid media, wave propogation is helical rather than planar. |
WBPhenotype:0000535
|
organism morphology variant
|
Animals exhibit variations in the form, structure or composition of any part of their anatomy compared to control animals. |
