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: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: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:0001150
|
polar body reabsorbed one two early emb
|
A polar body is reabsorbed in either the one cell- or the two-cell embryo. |
WBPhenotype:0001122
|
reversed asynchrony early emb
|
P1 divides before AB. |
