  • a Number of backgrounds tested.

  • b Number of individuals scored.

  • c Difference between mean residual of wild-type/Balancer and wild-type/Deficiency genotypes (* indicates effect in direction opposite to that predicted from original observation of Bloomington stock).

  • d P value associated with F-ratio for effect of genetic backgrounds.

  • e P value associated with F-ratio for effect of genotype (wt or Df chromosome).

  • f P value associated with F-ratio for genotype by background interaction effect.
