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:0000366
|
three fold arrest
|
Cessation of development that normally occurs in C. elegans 520-620min after the first cleavage at 20C, the stage between the 2-fold and fully elongated embryo. |
|
WBPhenotype:0000494
|
two fold arrest
|
Cessation of development that normally occurs in C. elegans 460-520 min after the first cleavage at 20C, the stage between the 1.5-fold and 3-fold embryo. |
|
WBPhenotype:0000361
|
lima bean arrest
|
Cessation of development at an intermediate stage in embryogenesis, immediately following the completion of gastrulation. In C. elegans this occurs around 350-390 minutes after first cleavage, cell number is at approximately 560 cells. At this time cell proliferation ceases and the embryo begins morphogenesis and elongation. The shape of the entire embryo within the eggshell resembles a lima bean (Wormatlas). |
|
WBPhenotype:0008001
|
embryonic cell fate specification variant
|
Any variation in the processes that govern acquisition of particular cell fates in the embryo, from the time of zygote formation until hatching compared to control. |
|
WBPhenotype:0000367
|
comma arrest emb
|
Cessation of development during the middle stage in embryogenesis of the worm in which the embryo is slightly folded within the eggshell (Wormatlas). |
