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:0001165
|
excess maternal pronucleus early emb
|
One-cell embryos have two or more maternal pronuclei. |
WBPhenotype:0001143
|
multiple nuclei early emb
|
Embryos contain more than one nucleus per cell in the inviable one- to four-cell embryo. |
WBPhenotype:0001156
|
pronuclear size defective early emb
|
Maternal or paternal pronucleus is either too small or too large. |
WBPhenotype:0001080
|
excessive blebbing early emb
|
Excessive shaking and movements are seen in the cell membrane or cytoplasm of one-cell or two-cell embryos. |
WBPhenotype:0001147
|
polar body defective early emb
|
Polar bodies are abnormal in the inviable one- to four-cell embryo. |
WBPhenotype:0001134
|
Aba ABp division axis defective early emb
|
ABa or ABp divide in the wrong orientation. |
WBPhenotype:0001124
|
ABa ABp EMS synchronous division early emb
|
EMS divides at the same time that ABa and ABp divide. |
WBPhenotype:0001126
|
cell cell contacts abnormal in four cell embryo
|
Aba, ABp, EMS, or P1 contacts fewer of its sister cells than in control embryos. |
