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:0000425
|
antibody staining reduced
|
Any variation that results in a decrease in the characteristic expression of a gene product, as detected by antibody staining, compared to control animals. |
WBPhenotype:0001136
|
embryonic morphology variant
|
Animals exhibit variations in the form, structure or composition of any of its parts during any developmental stage ranging from zygote formation to hatching compared to control. |
