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. |
WBPhenotype:0001020
|
embryonic lethal late emb
|
Animals die during the final stages of embryogenesis. In C. elegans, this lethality refers to death during the last (3-fold) stage of embryogenesis, which normally occurs 620-800 min after the first cleavage at 20C, the stage after elongation. |
