|
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:0001175
|
high incidence male progeny
|
Higher numbers of male progeny occur in the population compared to control populations. In C. elegans, the high incidence of males phenotype in a self-fertilizing hermaphrodite population is a result of an increase in X chromosome nondisjunction. |
WBPhenotype:0000059
|
larval arrest
|
The developmental program of the animals halts at any larval stage and thus fails to reach adulthood. In C.elegans, this occurs anytime during L1-L4 stage. |
WBPhenotype:0001165
|
excess maternal pronucleus early emb
|
One-cell embryos have two or more maternal pronuclei. |
WBPhenotype:0001143
|
multiple nuclei early emb
|
Embryos contain more than one nucleus per cell in the inviable one- to four-cell embryo. |
WBPhenotype:0001156
|
pronuclear size defective early emb
|
Maternal or paternal pronucleus is either too small or too large. |
WBPhenotype:0001147
|
polar body defective early emb
|
Polar bodies are abnormal in the inviable one- to four-cell embryo. |
