FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
CHES-1-likeunspecified homozygous females as well as hemizygous males are viable and fertile and no obvious morphological defects are observed in the adult male testes.
