|
WBPhenotype:0001260
|
oocyte morphology variant
|
Haploid female germ cells (oocytes) exhibit variations in their overall structure, appearance or contents compared to control. |
|
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: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:0001028
|
nuclear appearance variant
|
The morphological appearance of nuclei differs from control animals. |
|
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:0001946
|
pachytene progression during oogenesis variant
|
Developing oocytes show defects in their entry, progression through or exit from the pachytene stage compared to control animals. Pachytene is a cell cycle process comprising the steps by which a cell progresses through the third stage of prophase I in meiosis, in which crossing over occurs between a chromatid in one partner and another chromatid in the homologous chromosome. |
|
WBPhenotype:0000405
|
giant oocytes
|
The size of haploid female germ cells (oocytes) are significantly larger 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:0001973
|
germ cell compartment size variant
|
Any variation in germ cell compartment size 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:0001974
|
germ cell compartment small
|
Germ cell compartments are smaller than that of control animals. |
|
WBPhenotype:0001977
|
germ cell partition morphology variant
|
Any variation in the form or composition of the compartment partitions in the germline of females/hermaphrodites that exist when nuclei are still connected to a common cytoplasm (rachis), compared to control animals. |
|
WBPhenotype:0001979
|
gonad vesiculated
|
Animals contain small, fluid-filled, anucleate, spherical membrane-bound structures within the gonad. |
|
WBPhenotype:0001953
|
nuclear fallout
|
Nuclei have fallen out of developing germ cell compartments into the rachis. |
|
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. |
