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: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:0002570
|
embryonic arrest during gastrulation
|
Cessation of development during the gastrulation stage of embryonic development. In C. elegans, gastrulation occurs 100-290 minutes after first cleavage at 20 degrees Centigrade when the embryo develops from 28 cells to 421 cells (during the proliferating embryo life stage). |
