ommatidium (with ast1)
Heterozygotes have normal eyes.
Transheterozygotes with ast1 exhibit disranged ommatidia in nearly wild-type sized eyes. No wing vein abnormalities are found.
astK6/ast[+] is an enhancer of ommatidium phenotype of S54
astK6/ast[+] is an enhancer of ommatidium phenotype of EgfrE1
Dominantly enhances the eye phenotype of S54, S1, SL, Df(2L)S3, Df(2L)ast2 and EgfrE1. Double heterozygotes with spi1, rhove-1, Df(3R)by10 or sim1 do not have a visible phenotype. Does not dominantly alter the phenotype of ro1 or rhove-1 homozygotes. sim1/astK6 double heterozygotes do not have a visible phenotype.
Heterozygotes with S1 are viable.
Class 1 ast mutation.
