      ttkBG01491 homozygous males have significantly increased levels of aggression. (P < 0.05; Male aggression index = 14.45).

      (Edwards et al., 2009)

      ttkBG01491 mutant flies (males and females pooled) sleep on average 101.4 minutes longer per 24 hours than wild type flies. However a significant difference in 24 hour sleep time is seen between the sexes when they are analysed separately; no increase is seen in females, while males sleep on average 158.4 minutes longer than wild type.

      (Harbison and Sehgal, 2008)

      Homozygous males and females show a significant decrease in starvation resistance compared to controls.

      (Harbison et al., 2004)

      Mutants exhibit a quantitative gain of bristles.
