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.
Sry-δunspecified trans-heterozygous females have normal ovaries, but Sry-δunspecified hemizygous males have reduced testes, containing fewer bundles of sperm than wild-type.
