Fig. 2 Structure of the dpy-18/eT1 III; unc-46/eT1 V chromosomes showing the genotypes and
phenotypes of the self-progeny. (a) dpy-18 (III) and unc-46 (V) mutations are maintained heterozygously
by eT1. eT1 (III) segregates from chromosome III and eT1 (V) segregates from chromosome V. The initial
pairing regions are represented by gray dashed lines. (b) Punnet square showing resulting progeny.
Phenotypes are indicated for each progeny class. The normal chromosome III is shown as a dark gray
