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: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: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). |
