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:0001018
|
cytokinesis variant emb
|
Any variation that disrupts the cytoplasmic division of a cell during embryonic development compared to control. |
WBPhenotype:0001425
|
receptor mediated endocytosis defective
|
Animals exhibit defects in the cell-mediated uptake of external materials via receptor activity. Receptor-mediated endocytosis ensures specificity of transport and generally occurs via clathrin-coated pits and vesicles. In C. elegans, this is often judged by the lack of yolk uptake in oocytes. |
WBPhenotype:0001143
|
multiple nuclei early emb
|
Embryos contain more than one nucleus per cell in the inviable one- to four-cell embryo. |
