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:0001168
|
pseudocleavage absent early emb
|
No pseudocleavage is observed before or during pronuclear migration. |
WBPhenotype:0001155
|
pronuclei meet centrally early emb
|
The maternal and paternal pronuclei meet more centrally instead of meeting in the posterior end of the embryo. |
WBPhenotype:0001105
|
P0 spindle position abnormal
|
Altered P0 spindle placement causes either a symmetric first division, a division in which P1 is larger than AB, or a division in which the asymmetry is exaggerated such that AB is much larger than normal. |
WBPhenotype:0001143
|
multiple nuclei early emb
|
Embryos contain more than one nucleus per cell in the inviable one- to four-cell embryo. |
WBPhenotype:0001130
|
cytokinesis fails early emb
|
Cells of the embryo attempt to divide but fail to form two daughter cells. |
WBPhenotype:0001153
|
pronuclear migration failure early emb
|
Neither of the pronuclei migrate and they never meet. |
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:0001158
|
pronuclear breakdown asynchronous early emb
|
Instead of breaking down synchronously, the two pronuclei break down asynchronously in the inviable one-cell embryo. |
