Heterozygotes are WT and segregate WT, DpyUnc and dead eggs. mcDf3 is a deficiency very closely linked to lir-1 - not separable - which removes approx. 250 kb.

Recessive. Mild uncoordination and aldicarb resistance. Marked resistance to volatile anesthetics, isoflurane and halothane, is semi-dominant. Isolated in RM25 (essentially the same as TR403 - high copy Tc1). [NOTE (07/09/2020): a user has reported their stock received in Dec 2019 is not resistant to isofluorane]
