Heterozygotes are Unc. Segregates DpyUncs. Segregates Uncs which are recessive Mel. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

Heterozgyotes are WT and segregate WT, Dpys, and Ste or Mel. Pick wild-type individuals and check for correct segregation of progeny to maintain. bli-4 is suppressed by dpy-1 in hT2 homozygotes-only see a very few DpyBli.This strain cannot be distributed to commercial organizations. ep220 is likely Mel.
