||pat-10(h233) dpy-5(e61) unc-13(e450) I; sDp2 (I;f).
||Animals with the duplication are Unc. Animals which have lost the duplication are DpyUnc and arrest in late larval development.
||unc-38(x20) pat-10(st568)/unc-38(x20) dpy-5(e61) I.
||Heterozygotes are Unc non-Dpy and segregate Unc non-Dpy, DpyUnc and PATs. st568 is a recessive lethal causing a PAT phenotype (paralyzed embryoes, arrested elongation at 2-fold length).
||unc-38(x20) pat-10(st568) I; stEx14.
||Animals with the extrachromosomal array are Slow Rollers. Animals which have lost the array are Pats. Strain can be propagated by chunking.
