  1. aCourtship frequency varied between blocks (block 1: 12.5 ± 0.8 S.E.; block 2: 19.5 ± 0.8 S.E.; F1,77 = 27.7, P < 0.0001)
  2. Effects of the SPR- deficiency itself in unselected flies, or experimental evolution in SPR- and control populations, on the number of courtship events observed during male courtship of wild-type females
