qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP ok197 homozygotes (viable, sterile), wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. rad-50 homozygotes are viable, produce more than 95% dead eggs and a large fraction of the survivors are male (Him phenotype). Pick wild-type GFP+ and check for correct segregation of progeny to maintain. Reference: Hayashi M, et al. PLoS Genet. 2007 Nov;3(11):e191.

Age-dependent defect in meiotic double-strand break formation. Homozygous mutants produce elevated frequency of males and dead embryos resulting from defects in meiotic chromosome segregation. The frequency of both males and dead embryos increases in later broods. Reference: Rosu S, et al. PLoS Genet. 2013;9(8):e1003674.

Homozygotes produce 10-15% XO male self progeny; nondisjuction is correlated with an increased frequency of achiasmate X chromosomes in oocyte nuclei, and an unaltered distribution of X chromosome crossovers. Heterozygotes produce 1-2% male self-progeny. Homozygotes (and XO hemizygotes) are slower growing than WT; reduced male mating efficiency. me8 disrupts the function of the cis-acting X chromosome meiotic pairing center. Molecular studies show that the me8 chromosome carries a terminal deletion that removes >70 kb from the left end of the X chromosome, including the endogenous telomere; further, a segment of chromosome V has been translocated to the left end of X, and a new telomere has been added de novo to the end of the translocated segment.
