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: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:0001082
|
large cytoplasmic granules early emb
|
Abnormally large granules are observed in the cytoplasm of P0. |
WBPhenotype:0001119
|
cell cycle slow early emb
|
Embryos take longer to divide during the first and second cell divisions. |
WBPhenotype:0000689
|
maternal sterile
|
Animals produce no or very few embryos as a result of experimental treatment. This is in contrast to sterility due to genetic perturbations (maternal effect sterility). |
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:0001083
|
multiple cytoplasmic cavities early emb
|
Multiple vesicles, vacuoles, or cavities are seen during early embryogenesis. |
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. |
