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:0000059
|
larval arrest
|
The developmental program of the animals halts at any larval stage and thus fails to reach adulthood. In C.elegans, this occurs anytime during L1-L4 stage. |
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: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:0001109
|
P0 spindle rotation delayed early emb
|
P0 spindle rotates late in the inviable one- to four-cell embryo. |
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:0001083
|
multiple cytoplasmic cavities early emb
|
Multiple vesicles, vacuoles, or cavities are seen during early embryogenesis. |
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. |
