Insertion of a non-autonomous P-element within the first intron.
Alh1/Alh[+] is a suppressor of abnormal eye color phenotype of wph-p.lac+3/w1118
Alh1/Alh[+] is a suppressor of pigment cell phenotype of wph-p.lac+3/w1118
Eye colour: wph-p.lac+3/w1118 ; Alh1/+ females have a red eye colour. Eye colour: the eye colour of flies carrying wFab-7.5F24 in a w- background is darkened if they also carry Alh1/+.
Expression of AlhL.Scer\UAS under the control of Scer\GAL4da.G32 reduces the effect of Alh1 on the eye colour of females carrying wph-p.lac+3. Expression of AlhΔLZ.L.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4da.G32 does not alter the effect of Alh1 on the eye colour of females carrying wph-p.lac+3.
Selected as: a mutation that modifies the eye colour of flies carrying wph-p.lac+3.
