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:0001980
|
germ cell compartment expansion variant
|
Animals exhibit variations in the increase in size of compartments of the germline. In the C. elegans germline, syncytial compartments enlarge just prior to and coincident with the loop region, eventually abscising, to become fully enclosed germ cells (oocytes). |
|
WBPhenotype:0001972
|
germ cell compartment multinucleate
|
Germ cell compartments contain multiple nuclei. |
|
WBPhenotype:0000182
|
apoptosis reduced
|
Any perturbation that causes a decrease in the frequency of cell death by apoptosis compared to control animals. |
|
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:0001945
|
oocytes small
|
The size of haploid female germ cells (oocytes) are significantly smaller 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:0001948
|
diakinesis progression during oogenesis variant
|
Developing oocytes show defects in their entry, progression through or exit from the diakinesis stage compared to control animals. Diakinesis is a cell cycle process comprising the steps by which a cell progresses through the final stage of prophase I in meiosis; the transition to meiotic metaphase I. |
|
WBPhenotype:0001810
|
oocyte septum formation variant
|
Animals exhibit variations in the partitioning of oocytes from each other compared to control animals. |
|
WBPhenotype:0001971
|
germ cell compartment anucleate
|
Germ cell compartments do not contain a nucleus. |
|
WBPhenotype:0001979
|
gonad vesiculated
|
Animals contain small, fluid-filled, anucleate, spherical membrane-bound structures within the gonad. |
|
WBPhenotype:0001950
|
diplotene region organization variant
|
Animals exhibit variations from control animals in the organization of the germ cell nuclei in the gonad that are in the diplotene stage. In C. elegans the diplotene region follows the pachytene region and occurs just distal to, and coincident with, the loop in the gonad arm. In the diplotene region germ cell compartments become organized into a single file. |
|
WBPhenotype:0001954
|
diplotene absent during oogenesis
|
The diplotene stage is not observed in developing oocytes. 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:0001955
|
multiple nuclei oocyte
|
Haploid female germ cells (oocytes) contain more than one nucleus. |
|
WBPhenotype:0001956
|
oocytes lack nucleus
|
Haploid female germ cells (oocytes) lack a nucleus. |
|
WBPhenotype:0001941
|
rachis narrow
|
The nucleus-free core of germline cytoplasm in the gonad is not as wide as control animals. |
|
WBPhenotype:0001942
|
rachis absent
|
The nucleus-free core of germline cytoplasm in the gonad is missing. |
