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:0001151
|
pronucleus centrosomes defective early emb
|
Pronucleus is abnormal in the inviable embryo. |
|
WBPhenotype:0000777
|
polar body extrusion defective early emb
|
Unextruded or resorbed polar body(ies) leading to an extra PNs in P0 and/or extra karyomeres in AB/P1. |
|
WBPhenotype:0001177
|
embryo osmotic pressure sensitive early emb
|
Embryos rupture when placed on a 2% agar pad and covered with a coverslip. |
|
WBPhenotype:0001167
|
pseudocleavage defective early emb
|
Pseudocleavage is atypical in the inviable one-cell embryo. |
|
WBPhenotype:0001499
|
meiotic chromosome segregation variant
|
Variations in the process by which genetic material, in the form of chromosomes, is organized and then physically separated and apportioned to two or more sets during the meiotic cell cycle, compared to control. |
