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: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: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:0001792
|
nuclei small
|
Nuclei of specific cells are smaller 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:0001361
|
chromosome condensation variant
|
Any variation in the progressive compaction of dispersed interphase chromatin into threadlike chromosomes prior to mitotic or meiotic nuclear division, or during apoptosis, in eukaryotic cells compared to control. |
WBPhenotype:0001973
|
germ cell compartment size variant
|
Any variation in germ cell compartment size compared to control. |
WBPhenotype:0001810
|
oocyte septum formation variant
|
Animals exhibit variations in the partitioning of oocytes from each other compared to control animals. |
WBPhenotype:0001974
|
germ cell compartment small
|
Germ cell compartments are smaller than that of control animals. |
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:0001941
|
rachis narrow
|
The nucleus-free core of germline cytoplasm in the gonad is not as wide as control animals. |
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. |
