  • a +, characteristic rescued; ±, characteristic partially reserved. Several crosses were performed for each combination.

  • b No statistically significant deviation in the observed versus expected frequency (χ2 test).

  • c Statistical analysis was not performed.

  • d Statistically significant reduction in the observed versus expected frequency (χ2 test).

  • e Occasional male with one A6 sternite bristle.

  • f A6, one to six small bristles observed in the sixth sternite of males; wing, wings were slightly smaller than those of the wild type.

  • g ND, not determined.
