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:0001177
|
embryo osmotic pressure sensitive early emb
|
Embryos rupture when placed on a 2% agar pad and covered with a coverslip. |
WBPhenotype:0001165
|
excess maternal pronucleus early emb
|
One-cell embryos have two or more maternal pronuclei. |
WBPhenotype:0000040
|
one cell arrest early emb
|
Embryos fail to divide and arrest as one-cell embryos. |
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: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:0001156
|
pronuclear size defective early emb
|
Maternal or paternal pronucleus is either too small or too large. |
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. |
