WBPhenotype:0000688
|
sterile
|
Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. |
WBPhenotype:0001824
|
meiotic progression prophase variant
|
Animals exhibit variations in any process necessary for the progression through prophase during meiosis compared to control animals. |
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:0001215
|
germ cell mitosis variant
|
Variations in the mitotic expansion of germ cell populations or in the appearance of nuclei during development in the premeiotic region of the germline compared to control. |
