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:0000037
|
egg morphology variant
|
Any variation in the overall structure or appearance of fertilized oocytes that are laid compared to those laid by control animals. |
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. |
