^*Transformation of the second and third thoracic legs toward that of the first, seen as extra sex combs on the second and third legs of the males. Enhancements are categorized as complete (+++), strong (++), weak (+), or not more than seen with wild-type fathers (0). −, Denotes suppression of the indicated transformation. 

^† Transformation of the fourth abdominal segment toward the fifth, seen as black pigmentation appearing on the fourth abdominal tergite of the male. 

^‡ Transformation of the sixth abdominal segment to the seventh, seen as reduction of the sixth abdominal tergite in males and females. 

^§ Pharate lethality of males with the ph⁴¹⁰ mutation, indicated as lethal (l.) or viable (v.). 

^¶ Transformation of the first leg toward the second, seen as loss of sex comb teeth in the male. 

^‖ Transformation of the fifth abdominal segment toward the fourth, seen as loss of black pigment on the male fifth abdominal tergite.
