Temperature-sensitive allele of cyd-1. Phenotypically wild-type at 15C. At 25C, approximately one-third of q626 hermaphrodites were missing one distal tip cell (DTC) and approximately one-half of q626 males were missing the linker cell (LC). q626 also feminizes the XO gonad. q626 affects the production of SGP daughters in both sexes. There is also a maternal component since the mutant phenotype is almost fully penetrant in offspring of homozygous mothers, but less penetrant in offspring of heterozygous mothers.
