Pick wild-type to maintain. Heterozygotes are wild-type and should segregate wild-type heterozygotes, bcl-11 homozygotes (L1 larval arrest with starved appearance), and Dpy Unc homozygotes (Medium Dpy, Shrinker, poor backing). Maintain by picking wild-type and scoring for proper segregation of progeny. bcl-11 homozygotes have weak pharyngeal muscle contractions and pharyngeal lumen fails to open. cu10 is a 555 bp deletion (V:6360921..6361460). Predicted bcl-11 null allele. Reference: Vilimas, Tomas. (2004). Genes regulating ceh-22 and pharyngeal development of Caenorhabditis elegans.. University of Illinois at Chicago.
