| Description | Handling: Easy to manipulate. Rare exceptional progeny carry one half-translocation as a free duplication. Recombination frequency in unbalanced intervals increased on both LG I and LG X.
Recommended use: General balancing, strain maintenance
Growth characteristics: Original isolate marked with dpy-5 and unc-29. Homozygous inviable, probably breaks in let-363 (I). Heterozygotes exhibit reduced viability, low level of X chromosome nondisjunction (1.2%).
Summary: Translocation (rigorous proof of reciprocity lacking), moderately well characterized, very stable. Very effective balancer for left portion of LG I from left end to around let-363, and the right portion of LG X from the right end to between dpy-7 and unc-3. hT3(I), which disjoins from normal LG I, is probably LG X (right) translocated to LG I (right). hT3(X),which disjoins from normal LG X, is probably LG I (left) translocated to LG X (left).
