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:0001037
|
sterile progeny
|
Any variation that compromises the reproductive ability of the progeny of an animal. |
|
WBPhenotype:0001121
|
exaggerated asynchrony early emb
|
Asynchrony of the second division is exaggerated and P1 divides more slowly 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: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:0001141
|
nucleus reforms cell division remnant early emb
|
After division of either one-cell or two-cell embryos, the nuclei reappear next to the cell division remnant. |
|
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:0001126
|
cell cell contacts abnormal in four cell embryo
|
Aba, ABp, EMS, or P1 contacts fewer of its sister cells than in control embryos. |
|
WBPhenotype:0001127
|
EMS anterior extension fails early emb
|
The EMS blastomere fails to extend anteriorly and make extensive contact (hug) with the ABa blastomere. |
