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:0000730
|
apoptosis variant
|
Animals exhibit variations in any processes that influence the programmed cell death pathway. Induction of the apoptotic pathway triggers the activity of proteolytic caspases, which in turn lead to the destruction of the cell. |
WBPhenotype:0001355
|
gonad morphology variant
|
Variations in the form or composition of a specialized tissue of the reproductive tract that produces the male or female gametes compared to control (Wormatlas). |
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: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:0001945
|
oocytes small
|
The size of haploid female germ cells (oocytes) are significantly smaller compared to control. |
WBPhenotype:0001973
|
germ cell compartment size variant
|
Any variation in germ cell compartment size compared to control. |
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: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:0001974
|
germ cell compartment small
|
Germ cell compartments are smaller than that of control animals. |
WBPhenotype:0001979
|
gonad vesiculated
|
Animals contain small, fluid-filled, anucleate, spherical membrane-bound structures within the gonad. |
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: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. |
