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: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:0001165
|
excess maternal pronucleus early emb
|
One-cell embryos have two or more maternal pronuclei. |
WBPhenotype:0001082
|
large cytoplasmic granules early emb
|
Abnormally large granules are observed in the cytoplasm of P0. |
WBPhenotype:0001169
|
pseudocleavage exaggerated early emb
|
Embryos have more pronounced pseudocleavage than normal. |
WBPhenotype:0001119
|
cell cycle slow early emb
|
Embryos take longer to divide during the first and second cell divisions. |
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:0001156
|
pronuclear size defective early emb
|
Maternal or paternal pronucleus is either too small or too large. |
WBPhenotype:0001166
|
excess paternal pronucleus variant centrosome early emb
|
More than one paternal pronucleus is present in the inviable one-cell embryo or there is a defect in centrosome structure. |
WBPhenotype:0001134
|
Aba ABp division axis defective early emb
|
ABa or ABp divide in the wrong orientation. |
