WBPhenotype:0000684
|
fewer germ cells
|
Germ cell populations are reduced compared to control animals. |
WBPhenotype:0000291
|
no oocytes
|
Hermaphrodites lack fully specialized female gametes that are competent for fertilization. |
WBPhenotype:0001036
|
sterile F1
|
Any variation that compromises the reproductive ability of an F1 generation animal. |
WBPhenotype:0001301
|
P granule abnormal
|
Localization or structural appearance of P-granules is altered compared to control. P-granules are cytoplasmic structures associated with germ nuclei in the C. elegans gonad, and are localized exclusively to germ cells, or germ cell precursors, throughout the life cycle. |
WBPhenotype:0000863
|
male fertility reduced
|
Males exhibit a reduction in the production of new individuals owing to defects in sperm competence and/or function compared to control animals. |
WBPhenotype:0000356
|
spermatogenesis delayed
|
The progression of immature germ cells to functional sperm is retarded compared to control. |
