      Eyes small and rough; wing veins L2, L3, L4 and L5 do not always extend to margin. S1 +/+ ast1 has very small eyes with fused facets; veins L2 to L5 incomplete at tip. S1 ast1/+ ast1 has slightly larger eye than S1 +/+ ast1. S1 ast1/+ + resembles S1 +/+ +. S +/+ ast and ast/ast partially suppress px and net. Eyes of ast1/E(S)1 rough. Enhanced by: E(S). RK2.
       
      Homozygotes have rough eyes. Wings veins L2, L3, L4 and L5 occasionally have terminal gaps. Heterozygotes occasionally have a very slightly roughened eye, but are usually inseparable from wild-type.
      Intercalary and terminal gaps in all veins in an erratic fashion and asymmetrically in the two wings of the same individual. Abnormal eye morphology.
      Transheterozygotes with astB612, astK3 or astK12 exhibit disranged ommatidia in eyes that are one to three quarters wild type size. Wing veins L2, L3, L4 and L5 do not reach the wing margin in the majority of males and occasionally in females. Transheterozygotes with astK11 exhibit disranged ommatidia in nearly wild-type sized eyes. No wing vein abnormalities are found. Transheterozygotes with astK2, astK5, astK7, astK14, astK15, astK16, astK17, astK18, astK19 or astK21 exhibit disranged ommatidia in eyes that are one to three quarters wild type size. Wing veins L2, L3, L4 and L5 do not reach the wing margin in the majority of males and occasionally in females. Transheterozygotes with astK6 or astK20 exhibit disranged ommatidia in nearly wild-type sized eyes. No wing vein abnormalities are found. Transheterozygotes with astK13 exhibit ommatidia that are very jumbled and often fused. Eyes are less than one-quarter wild type size. Wing vein abnormalities are very pronounced and present in nearly all males and females. Transheterozygotes with astK9 exhibit ommatidia that are very jumbled and often fused. Eyes are less than one-quarter wild type size. Wing vein abnormalities are very pronounced and present in nearly all males and females.
      Mutants have a rough eye phenotype with minor defects in ommatidial assembly.
      ast1/Df(2L)ast4 embryos have defects in the development of a subset of somatic muscles, especially muscles LL1 and DO4.

      Reference
      Dominantly enhances the S1 eye phenotype: double heterozygotes have extremely small, diamond-shaped eyes in which many of the facets are fused and the remainder are irregular in size and distribution. The phenotype is dominantly enhanced by E(S)1; ast1 E(S)1 double heterozygotes have rough eyes. Partially suppresses the phenotype or netunspecified or pxunspecified homozygotes. S1/ast1 tends to completely suppress the phenotype of netunspecified or pxunspecified homozygotes.
      S51/ast1 flies have an extremely small and narrow eye, with a glasslike effect. The distal ends of wing veins L2 to L5 are missing to various degrees.
      The suppression of the sev6 R7 phenotype by SosJC2 is almost entirely reversed if the flies are also made heterozygous for ast1 or ast4. In S1/ast1 transheterozygotes the eyes are reduced in size and many ommatidia are missing.
