Hets are WT and segregate WT, dead eggs, and larval lethals (eDf24 homozygotes). eDf24 = let(e2000).

Wild type, segregating Unc-101 (hIn1[unc-101] homozygotes), wild type and arrested embryos. eDf6 homozygote arrests as unhatched embryo at lima bean stage. Pick WT and check for correct segregation of progeny to maintain. This strain was generated by the Genetic Toolkit project, which should be acknowledged in any publications resulting from its use: The Genetic Toolkit is funded by the NIH National Center for Research Resources (NCRR) (USA) to Ann M. Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to Ann Rose.

meDf6; yDp13 is WT hermaphrodite which is Him. 27% of self-progeny are WT males. yDp13 recombines with X, but such recombination is greatly reduced in an meDf6 background. Maintain by picking L4 hermaphrodites and checking to make sure they give lots of dead eggs and lots of males. [yDp13 XO males with an intact X chromosome are >90% inviable.]

meDf6; yDp15 is WT hermaphrodite which is Him. 23% of self-progeny are WT males. yDp15 recombines with X, but such recombination is greatly reduced in an meDf6 background. Maintain strain by picking L4 hermaphrodites and making sure they give lots of dead eggs and lots of males. [yDp15 XO males with an intact X chromosome are >90% inviable.]
