WBPhenotype:0000823
|
germline proliferation variant
|
Nuclear divisions in the germ line are either expanded are reduced compared to control. |
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:0000691
|
gonad development variant
|
Variations in the progression of the organ that produces gametes over time, from its formation to the mature structure compared to control. |
WBPhenotype:0001348
|
chromosome morphology variant
|
Variations in the form or composition of a structure in the cell nucleus which contains the genetic material encoded as DNA and surrounded by histone proteins and other regulatory elements compared to control. In C. elegans the normal cell contains 5 pairs of 'autosomes' and one or two X chromosomes (Wormatlas). |
WBPhenotype:0000689
|
maternal sterile
|
Animals produce no or very few embryos as a result of experimental treatment. This is in contrast to sterility due to genetic perturbations (maternal effect sterility). |
