WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
WBPhenotype:0000692
|
male sterile
|
X0 animals fail to generate viable cross-progeny. |
WBPhenotype:0000050
|
embryonic lethal
|
Animals die during embryonic development. In C. elegans, often assayed as refractile eggs that fail to hatch; when applied to large-scale RNAi screens in C. elegans, more than 10% of embryos die. |
WBPhenotype:0000239
|
vulval cell lineage variant
|
The descendants of a vulval precursor cell exhibit altered developmental programs compared to their counterparts in control animals. In C. elegans, the VPCs are P3.p-P8.p. |
WBPhenotype:0000775
|
meiosis variant
|
Variations in the specialized nuclear and cytoplasmic divisions of a single diploid cell, whose specific outcome is the formation of four haploid daughter cells compared to control. Meiosis occurs during the formation of gametes. |
WBPhenotype:0000038
|
exploded through vulva
|
The animal is ruptured at the vulva and displays an extrusion of internal organs at the site of rupture. |
WBPhenotype:0000188
|
gonad arm morphology variant
|
Any variation in the 'arm-like' form, structure or composition of the specialized tissue of the reproductive tract that produces gametes compared to control. In C. elegans the reproductive tract in the hermaphrodite has two equivalent gonad 'arms', while the male has a one-armed gonad. |
