WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
|
WBPhenotype:0000291
|
no oocytes
|
Hermaphrodites lack fully specialized female gametes that are competent for fertilization. |
|
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:0001972
|
germ cell compartment multinucleate
|
Germ cell compartments contain multiple nuclei. |
|
WBPhenotype:0000184
|
apoptosis fails to occur
|
Cells do not undergo the form of programmed cell death characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), classically little or no ultrastructural modifications of cytoplasmic organelles, plasma membrane blebbing (but maintenance of its integrity until the final stages of the process) and engulfment by resident phagocytes. |
|
WBPhenotype:0000182
|
apoptosis reduced
|
Any perturbation that causes a decrease in the frequency of cell death by apoptosis compared to control animals. |
|
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: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:0001944
|
oocyte number decreased
|
A decreased number of celullarized haploid female germ cells (oocytes) are present in the gonad compared to control. |
|
WBPhenotype:0001567
|
nuclei enlarged
|
Nuclei of specific cells are larger compared to control animals. |
|
WBPhenotype:0001810
|
oocyte septum formation variant
|
Animals exhibit variations in the partitioning of oocytes from each other compared to control animals. |
|
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: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:0001978
|
germ cell partition absent
|
Animals lack germ cell partitions (germ cell compartments). |
|
WBPhenotype:0001953
|
nuclear fallout
|
Nuclei have fallen out of developing germ cell compartments into the rachis. |
|
WBPhenotype:0001955
|
multiple nuclei oocyte
|
Haploid female germ cells (oocytes) contain more than one nucleus. |
|
WBPhenotype:0001943
|
rachis wide
|
The width of the nucleus-free core of germline cytoplasm in the gonad is larger compared to control animals. |
