The fitness component(s) responsible for the competitive disadvantage of flies carrying mutant alleles of Rst(1)JH have been analysed in Rst(1)JH1, Rst(1)JH2, Rst(1)JH3, Rst(1)JHD29 and Rst(1)JHN6 flies. Small but significant differences were found between the pooled Rst(1)JH alleles and wild-type for pupal developmental time, pupal mortality, and early adult fecundity. These differences results in a large competitive disadvantage.
