- mutagen induced apoptosis variant
Programmed cell death of germ cells caused by exposure to physical or chemical DNA-damaging agents does not occur to the same extent as it does in control animals.
- homolog association variant
The association of homologs during diakinesis and the maintenance of their association through meiosis I as well as the preservation of centromeric cohesin between sister chromatids does not proceed as it does in control animals.
- L2 arrest
The developmental program of the animals does not continue past the second larval stage (L2).
- L1 arrest
The developmental program of the animals does not continue past the first larval stage (L1).
