|AV308||C. elegans||him-14(it21)/mnC1 [dpy-10(e128) unc-52(e444)] II. Show Description
Heterozygotes are wild-type and segregate wild-type heterozygotes, DpyUncs (mnC1 homozygotes), and him-14 homozygotes that produce >95% dead embryos and 45% males. Among these surviving progeny, cytologically they have 12 univalents in diakinesis-stage oocytes owing to a failure to form crossovers during meiosis.
