      Detailed Description
      Statement
      Reference

      The projections of Or47b-positive ORNs to the VA1lm/VA1v glomerulus is unaffected in Or47b2 homozygotes.

      Or47b2 mutant males do not show elevated male-male courtship towards oenocyte-eliminated target males, although aggression levels are unaffected.

      Or47b2 mutant males exhibit normal latencies to copulate with virgin females. The frequency of unilateral wing extensions toward females also does not show a statistically significant difference compared to controls.
