WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
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:0000054
|
larval lethal
|
The animal dies at any time between hatching and onset to adulthood. |
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:0001026
|
nuclear morphology variation early emb
|
Animals exhibit variations in the form, structure or composition of the membrane enclosed organelle which contains most of the cell's genetic material during the early embryonic stage compared to control animals (Wormatlas). |
