Homozygous viable. Deletion of 171 bp with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break. Left flanking sequence: CACTGGCTGTCGCTGTCGTCTCGACTGCCG. Right flanking sequence: AGGAATTGGCGAAATTGTACGAGGAGAAAG. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.

Heterozygotes are WT and segregate WT, Unc, Ste/Mel, and dead eggs. ssl-1(n4077) deletion removes 683 nucleotides from the ssl-1 locus (Y111B2A.23). Relative to the first nucleotide of the predicted initiator ATG, the deletion begins at about nt. 5075 and ends at about nt. 5757 to give the junction sequence GATATACAC/AGACCTAAT.
