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:0001139
|
nuclear envelope assembly variant early emb
|
Nuclear envelope does not reassemble properly. |
WBPhenotype:0001163
|
pronucleus formation failure early emb
|
Either the maternal or paternal pronucleus is absent. |
WBPhenotype:0001130
|
cytokinesis fails early emb
|
Cells of the embryo attempt to divide but fail to form two daughter cells. |
WBPhenotype:0002501
|
ectopic cleavage furrow early emb
|
One or more cells of the early embryo (one-cell stage to four-cell stage) exhibit one or more cleavage furrows in locations not normally found in control cells. |
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:0001161
|
maternal pronucleus indistinct early emb
|
Maternal pronucleus has a blurry appearance. The nuclear envelope does not have a crisp circular shape. |
