Approximately 60-70% of hemizygous embryos survive. Approximately 30% of hemizygous males survive to adulthood. The male gonad is reduced in size and contains very few spermatozoa bundles, although the seminal vesicles and ejaculatory bulb appear normal. Female Sry-δSF1/Df(3R)X3F escapers have a reduced life span.
Sry-δSF1 has lethal phenotype, suppressible by Dpse\Sry-deltatFa
Dpse\Sry-deltatFa, Sry-δSF1 has viable phenotype
Sry-delta[+]/Sry-δSF1 is a non-suppressor of female germline stem cell phenotype of piwi2
Lethality is completely rescued by one copy of Dpse\Sry-δtFa.
Introduction of P{sryDB56,ry+} causes partial rescue of the mutant phenotype, the labrum is still affected.
