3 Phenotype
| Identifier | Name | Description |
|---|---|---|
| WBPhenotype:0000154 | reduced brood size | The characteristic number of offspring produced is lower compared to that of control animals. |
| 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:0000059 | larval arrest | The developmental program of the animals halts at any larval stage and thus fails to reach adulthood. In C.elegans, this occurs anytime during L1-L4 stage. |
