Heterozygotes are Unc and segregate Unc, RolPar (adult homozygotes lay eggs that don't hatch) and dead eggs. nT1[unc-?(n754) let-?] is dominant Unc and recessive lethal. Strict maternal effect. sc8 previously called rol-4(sc8).

zuIs45 [nmy-2p::nmy-2::GFP + unc-119(+)] V. Balanced heterozygotes are Unc and segregate Unc (heterozygotes), Rol Par (sqt-3 par-1 homozygotes; maternal effect lethal), and dead eggs (nT1 homozygotes). NMY-2::GFP is expressed in the germline and somatic gonad. Cross of JJ1473 and KK288. Unknown if unc-119(ed3) is still present or homozygous in background. Reference: Small LE & Dawes AT.

meGFP inserted between P121 and V122 of endogenous MEG-3. qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP par-1 homozygotes (viable, lay dead embryos), wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. Pick wild-type GFP+ and check for correct segregation of progeny to maintain. Replacement of threonine 983 with alanine eliminates PAR-1 asymmetry. Reference: Folkman AW & Seydoux G.

qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP par-1 homozygotes (viable, lay viable progeny that are completely sterile), wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. Pick wild-type GFP+ and check for correct segregation of progeny to maintain. par-1(ax4208) removes the KA1 domain from a GFP-tagged version of PAR-1. Reference: Folkman AW & Seydoux G.
