CB3967 C. elegans tra-2(e2046) II. Show Description
Obligate XX female, XO male strain. Maintain by mating. Viable 15-25C. e2046 is a dominant mutation transforming XX into fertile female; minimal effect on XO.
CB4050 C. elegans tra-2(e2046e2115) unc-4(e120) II; sup-7(st5) X. Show Description
Phenotypically wildtype XX hermaphrodite at 20C; poor viability and fertility at 25C. Rare XO animals are hermaphrodite due to suppression of amber mutation e2115 and consequent transformation of XO due to tra-2(e2046) gain-of-function. Reference: Hodgkin & Albertson (1995) PMID: 8647390.
