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:0001036
|
sterile F1
|
Any variation that compromises the reproductive ability of an F1 generation animal. |
WBPhenotype:0000812
|
germ cell development variant
|
Variations in the progression of the immature germ cell over time, from its formation from precursors to the mature structure (gamete) compared to control. |
WBPhenotype:0000049
|
postembryonic development variant
|
