WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
|
WBPhenotype:0000290
|
sperm absent
|
Animals lack fully specialized male gametes that are competent for fertilization. |
|
WBPhenotype:0000291
|
no oocytes
|
Hermaphrodites lack fully specialized female gametes that are competent for fertilization. |
|
WBPhenotype:0001038
|
tumorous germline
|
Germ cells do not exit the mitotic cycle, resulting in a expansion of the unspecialized germ cell population compared to control. |
|
WBPhenotype:0000837
|
hermaphrodite gonadal lineage variant
|
The descendants of a gonadal precursor cell exhibit altered developmental programs in the hermaphrodite compared to their counterparts in control animals. |
|
WBPhenotype:0001962
|
missing distal tip cells
|
Animals produce less distal tip cells compared to controls. |
|
WBPhenotype:0000220
|
vulva cell fate specification variant
|
Any aberrancy in the processes that govern acquisition of vulval cell fates compared to control animals. |
|
WBPhenotype:0001495
|
cell division precocious
|
Cells divide at an earlier stage of development compared to control animals. |
|
WBPhenotype:0000668
|
endomitotic oocytes
|
Any variation that results in the presence of mature oocytes with distended polyploid nuclei. In C. elegans, such oocytes mature and exit diakinesis, but are often not properly ovulated or fertilized. |
|
WBPhenotype:0001033
|
proximal germ cell proliferation variant
|
Any variation in the spatial pattern of proliferation and differentiation in the germ line compared to control. In C. elegans, this refers to an ectopic mass of proliferating germ cells that occupies the proximal adult germ line, a region normally occupied by gametes. |
|
WBPhenotype:0001928
|
extra gonad arms
|
Animals produce an excess number of gonad arms compared to controls. |
|
WBPhenotype:0001944
|
oocyte number decreased
|
A decreased number of celullarized haploid female germ cells (oocytes) are present in the gonad compared to control. |
|
WBPhenotype:0001636
|
excess intestinal cells
|
Animals contain an excess number of intestinal cells compared to control. In C. elegans, intestinal cells are derived from E-blastomere. The overproduction of intestinal tissues is a result of other blastomeres adopting an E-like fate or excess cell proliferation in the E lineage. |
|
WBPhenotype:0001493
|
VPC cell division precocious
|
VPCs (vulval precursor cells) divide at an earlier stage of development compared to control animals; in C. elegans, VPCs divide in the mid-L3 stage to generate the 22 cells that comprise the vulva. |
|
WBPhenotype:0000667
|
gonad displaced
|
The specialized tissue of the reproductive tract that produces gamete is shifted from its customary place as defined by control. |
|
WBPhenotype:0001993
|
fewer gonadal sheath cells
|
Animals exhibit fewer somatic sheath cells surrounding each gonad arm, compared to controls. |
|
WBPhenotype:0001992
|
extra gonadal sheath cells
|
Animals exhibit an increase in the number of somatic sheath cells surrounding each gonad arm compared to controls. |
