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:0001951
|
pachytene region organization variant
|
Animals exhibit variations from control animals in the organization of the germ cell nuclei in the pachytene stage region of the gonad. In C. elegans the pachytene region begins just proximal to the germline's transition zone, where germ cells coordinately switch into the leptotene/zygotene stage from the premeiosis stage (WormAtlas). |
|
WBPhenotype:0000183
|
apoptosis increased
|
Any perturbation that causes an elevation in the frequency of cell death by apoptosis compared to control animals. |
|
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:0001180
|
accumulated germline cell corpses
|
Animals exhibit an increase in the quantity of germ line cells that have undergone programmed cell death but have not been engulfed. |
|
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:0001945
|
oocytes small
|
The size of haploid female germ cells (oocytes) are significantly smaller compared to control. |
|
WBPhenotype:0001971
|
germ cell compartment anucleate
|
Germ cell compartments do not contain a nucleus. |
|
WBPhenotype:0001969
|
germ cell compartment morphology variant
|
Any variation in the form or composition of the compartments in the germline of females/hermaphrodites compared to control animals. In C. elegans these compartments contain a nucleus and are connected to a common cytoplasm (rachis). These compartments eventually undergo cellularization and become oocytes. |
|
WBPhenotype:0001975
|
germ cell compartment large
|
Germ cell compartments are larger than that of control animals. |
|
WBPhenotype:0001953
|
nuclear fallout
|
Nuclei have fallen out of developing germ cell compartments into the rachis. |
|
WBPhenotype:0001956
|
oocytes lack nucleus
|
Haploid female germ cells (oocytes) lack a nucleus. |
|
WBPhenotype:0001949
|
diakinesis region organization variant
|
Animals exhibit variations from control animals in the organization of the germ cell nuclei in the gonad that are in the diakinesis stage. In C. elegans the diakinesis region occurs in the proximal gonad arm and is preceded by the diplotene region. In the diakinesis region oocytes arrest until oocyte maturation occurs. |
