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:0001106
|
spindle orientation variant AB or P1 early emb
|
The orientation of the spindle is aberrant in either the AB or the P1 cell. |
WBPhenotype:0001177
|
embryo osmotic pressure sensitive early emb
|
Embryos rupture when placed on a 2% agar pad and covered with a coverslip. |
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:0001123
|
synchronous second division early emb
|
AB and P1 divide synchronously. |
WBPhenotype:0001109
|
P0 spindle rotation delayed early emb
|
P0 spindle rotates late in the inviable one- to four-cell embryo. |
WBPhenotype:0001150
|
polar body reabsorbed one two early emb
|
A polar body is reabsorbed in either the one cell- or the two-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:0001125
|
P2 EMS synchronous division early emb
|
P2 and EMS divide synchronously. |
WBPhenotype:0001127
|
EMS anterior extension fails early emb
|
The EMS blastomere fails to extend anteriorly and make extensive contact (hug) with the ABa blastomere. |
WBPhenotype:0001112
|
aster AB resembles P1 aster early emb
|
The morphology of the AB aster resembles that of the P1 aster in the inviable one- to four-cell embryo. |
