This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).
Df(2R)knSA3 fails to complement Df(2R)Jp1.
Homozygous embryos show defects in salivary gland invagination and migration.
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
Intermediate second site non-complementing phenotype with zipEbr and zipmhc-c6.1 : malformed phenotype penetrance 25-75%.
Shows no maternal enhancement of dpphr4.
Does not uncover Dsim\jba in D.melanogaster/D.simulans hybrids. Does not uncover Dsim\pm in D.melanogaster/D.simulans hybrids.
Homozygous embryos are very abnormal compared to wild-type.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
