rn19 is a null allele for the "rn" mutant phenotype but does not cause "roe" phenotypes. rn19/Df(3R)rn20 adults show fusion of tarsal segments.
Dissections of male and female internal genitalia revealed no mutant phenotype in the male, but seminal receptacle in female is only half the wild type length. There is no other mutant phenotype in the female genital disc derivatives, even though the m5.3 expression crosses the primordia of the uterus.
