WBPhenotype:0000977
|
somatic gonad morphology variant
|
Animals exhibit variations in the form, structure or composition of the components of the gonad that are separate from the germline proper compared to control animals. |
|
WBPhenotype:0001357
|
male gonad morphology variant
|
Variations in the form or composition of a specialized tissue of the reproductive tract that produces the male 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: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:0001957
|
gonad small
|
A decrease in size of the specialized tissue of the reproductive tract that produces the male or female gametes compared to control (Wormatlas). |
|
WBPhenotype:0001825
|
rudimentary gonad
|
Animals have very few or no germline nuclei and gonad arms that are very small or missing. |
|
WBPhenotype:0001979
|
gonad vesiculated
|
Animals contain small, fluid-filled, anucleate, spherical membrane-bound structures within the gonad. |
|
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:0001958
|
gonad degenerate
|
Animals contain a gonad that initially functioned, but subsequently stopped. In hermaphrodites or females there is often the presence old embryos and/or hatched larva, but no young embryos, in the uterus. |
|
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. |
