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: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: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:0001948
|
diakinesis progression during oogenesis variant
|
Developing oocytes show defects in their entry, progression through or exit from the diakinesis stage compared to control animals. Diakinesis is a cell cycle process comprising the steps by which a cell progresses through the final stage of prophase I in meiosis; the transition to meiotic metaphase I. |
|
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:0001971
|
germ cell compartment anucleate
|
Germ cell compartments do not contain a nucleus. |
|
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: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: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:0001943
|
rachis wide
|
The width of the nucleus-free core of germline cytoplasm in the gonad is larger compared to control animals. |
