WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
WBPhenotype:0001260
|
oocyte morphology variant
|
Haploid female germ cells (oocytes) exhibit variations in their overall structure, appearance or contents compared to control. |
WBPhenotype:0001952
|
germline nuclear positioning variant
|
Variations in the directed movement/or positioning of a nucleus to a specific location within the germline compartment compared to control. |
WBPhenotype:0001982
|
cell membrane organization biogenesis variant
|
Variations in the process(es) involved in the assembly, transport, arrangement or disassembly of cell membrane structures or components compared to control. |
WBPhenotype:0001940
|
rachis morphology variant
|
Any variation in the form, structure or composition of the nucleus-free core of germ line cytoplasm in the gonad compared to control animals. In the C. elegans germline, nuclei exiting mitosis and entering meiosis are arranged along the cortex of the germline, partially enclosed by cellular membrane, forming a nucleus-free core of germline cytoplasm, called the rachis. |
WBPhenotype:0001947
|
diplotene progression during oogenesis variant
|
Developing oocytes show defects in their entry, progression through or exit from the diplotene stage compared to control animals. Diplotene is a cell cycle process comprising the steps by which a cell progresses through the fourth stage of prophase I in meiosis, in which the homologous chromosomes begin to separate and the synaptonemal complex dissolves. |
WBPhenotype:0001810
|
oocyte septum formation variant
|
Animals exhibit variations in the partitioning of oocytes from each other compared to control animals. |
WBPhenotype:0001979
|
gonad vesiculated
|
Animals contain small, fluid-filled, anucleate, spherical membrane-bound structures within the gonad. |
WBPhenotype:0001941
|
rachis narrow
|
The nucleus-free core of germline cytoplasm in the gonad is not as wide as control animals. |
