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:0000031
|
slow growth
|
Any variation that causes a reduction in growth rate compared to control. |
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:0001082
|
large cytoplasmic granules early emb
|
Abnormally large granules are observed in the cytoplasm of P0. |
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:0001153
|
pronuclear migration failure early emb
|
Neither of the pronuclei migrate and they never meet. |
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:0001131
|
loose mitotic furrow early emb
|
Once formed, the mitotic furrow can "slide"laterally. |
WBPhenotype:0001104
|
P0 spindle absent early emb
|
No mitotic spindle is seen in P0. |
