  • C1 and C3 denote chromosomes 1 and 3, respectively; H refers to selection for high and L to selection for low sternopleural (ST) or abdominal (AB) bristle number. NS, P > 0.05; * 0.01 < P < 0.05; ** 0.001 < P < 0.01; *** 0.0001 < P < 0.001; **** P < 0.0001.

  • a Among-line variance component from single-sex analyses of variance of bristle number. P values are from F-ratio tests of significance of the line term in these analyses.

  • b The sum of the between-replicate and within-replicate (error) variance components from single-sex analyses of variance of bristle number.

  • c The genetic correlation between the sexes computed from variance components as described in the text. P values are from F-ratio tests of significance of the sex × line interaction term from combined-sex analyses of variance and indicate whether the genetic correlations are significantly different from unity.
