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: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: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: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: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: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:0001955
|
multiple nuclei oocyte
|
Haploid female germ cells (oocytes) contain more than one nucleus. |
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. |
