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.

pk690 is a deletion allele within the gene C32E8.7. The deletion is stable in the homozygous state and has no obvious phenotype. Can verify the presence/homozygosity of the deletion by PCR using the following primers: AL1: 5'-CGACGACACTCCATTATTCC-3' AR1: 5'-CCAGTCCTGCAAAAATGCTC-3'. A product of about 3.7 kb is obtained from WT worms, while a product of about 1 kb is obtained from NL2003 worms. The deletion has been sequenced and covers position -354 to +2276.
