Homozygous females have an almost completely null y[-] pigmentation phenotype in the wings and in the body.
y2/y1#8 females show nearly wild-type pigmentation levels in the wing and body.
Dp(1;2)y2A reduces the level of complementation that is normally observed between y1#8 and y2 (the progenitor of Dp(1;2)y2A), such that the body and wing cuticle of y1#8/Dp(1;2)y2A females has a more severe pigmentation phenotype than that of y1#8/y2 females.
Dp(1;4)y2B reduces the level of complementation that is normally observed between y1#8 and y2 (the progenitor of Dp(1;4)y2B), such that the body and wing cuticle of y1#8/Dp(1;4)y2B females has a more severe pigmentation phenotype than that of y1#8/y2 females.
Dp(1;4)y2C reduces the level of complementation that is normally observed between y1#8 and y2 (the progenitor of Dp(1;4)y2C), such that the body and wing cuticle of y1#8/Dp(1;4)y2C females has a more severe pigmentation phenotype than that of y1#8/y2 females.
y2 flies have a pale abdomen with dark bristles.
y2 mutants exhibit discoloration of the cuticle, especially apparent in the abdomen.

Expression of Top2GD4570 under the control of Scer\GAL4arm.PS results in a decrease in gypsy insulator function, manifested by a change in body colour from yellow to black in y2 mutants.
Expression of su(Hw)GD4493 under the control of Scer\GAL4arm.PS results in a decrease in gypsy insulator function, manifested by a change in body colour from yellow to black in y2 mutants.
The cuticle colour of y2; Cp190En15/Cp190P11 adults is darker than that of y2 flies.
y2 Cp190En15/+, mod(mdg4)T6 flies have more darkly pigmented body cuticle and wings than y2; mod(mdg4)T6 flies.
y2 mod(mdg4)ul double mutant flies have a dappled abdomen with pale bristles.
y2 mod(mdg4)T6 double mutant flies have a dappled abdomen with pale bristles.
Body colour: y2 ; mod(mdg4)Z3-3401/mod(mdg4)T16 and mod(mdg4)T6/mod(mdg4)T16 flies have a y- phenotype (yellow bristles, wings and bodies).
Body colour: the y2 phenotype (black bristles, yellow body and wings) is not altered by mod(mdg4)Z3-5578/mod(mdg4)T16.
y2 mod(mdg4)ul double mutants exhibit a suppression of the y2 cuticle phenotype, and so exhibit a more pigmented abdomen.
The transheterozygote lwr05486/smt304493 suppresses the mod(mdg4)ul suppression of the y2 cuticle phenotype, leading to a lighter coloration of the abdomen (due to a reduction in y expression).These phenotypic changes occur in approximately 30% of the mutant flies, with the remaining 70% displaying a continuum of less-pronounced effect. The phenotype is also particularly pronounced in females, although it is detectable in both sexes.
The transheterozygote lwr02858/smt3k06307 suppresses the mod(mdg4)ul suppression of the y2 cuticle phenotype, leading to a lighter coloration of the abdomen (due to a reduction in y expression). These phenotypic changes occur in approximately 30% of the mutant flies, with the remaining 70% displaying a continuum of less-pronounced effect. The phenotype is also particularly pronounced in females, although it is detectable in both sexes.
Body colour: y2 ; Df(2R)P34/+ flies show increased production of black pigment in the abdomen compared to y2 flies.
Body colour: y2 ; mod(mdg4)ul/+ flies show increased production of black pigment in the abdomen compared to y2 flies.
Body colour: y2 flies expressing ToporsdsRNA.Scer\UAS under the control of Scer\GAL4Act show increased production of black pigment in the abdomen compared to y2 flies.
Body colour: y2 ; mod(mdg4)ul flies that are also expressing ToporsScer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4Act have a very low level of black pigment in the abdomen.
Body colour: y2 ; Lam04643/+ ; mod(mdg4)ul flies show increased production of black pigment in the abdomen compared to y2 ; mod(mdg4)ul flies.
e(y)21 y2 males show reduced viability compared to wild type. 14% of the mutant males have distorted tergites.
Body colour: e(y)21 y2 males have reduced pigmentation of head and thorax bristles compared to wild type.
The reduced viability, reduced pigmentation of head and thorax bristles and distorted tergite phenotype that is seen in e(y)21 y2 males is not rescued by e(y)2bsu(Hw).PK.
y2 ct6; Df(3R)E(mod)4-1P11/Cp190H53-2 flies, which are removed from the pupal cases very late in pupal development, display a black cuticle coloration in the abdomen, indicating complete suppression of y2. The shape and margins of the wings are normal, indicating complete suppression of ct6.
The wings of y2 ct6; Cp190H4-1 male flies are rounder in shape, suggesting that ct6 is partially suppressed, whereas the bristles are yellow, indicating that the y2 phenotype is altered. The body cuticle colour is only slightly darker in the background of the Cp190H4-1 mutation.

Pigmentation of the thoracic and leg bristles is reduced in combination with e(y)11.
y2; mod(mdg4)ul males have variegated abdominal pigmentation with individual spots of wild-type dark pigment against a lighter pigmented background in the last two abdominal segments. This variegated phenotype is suppressed if the flies are also carrying lawcp1; the areas of lighter pigmentation increase at the expense of darkly pigmented regions so that the phenotype is closer to y2 rather than y2 ; mod(mdg4)ul flies.
su(Hw)NoAD, su(Hw)V and su(Hw)Δ283 suppress the mutant phenotype.

Mutates to y1-like alleles with X-rays or mutator gene mutations.
y2/Y; mod(mdg4)ul/+ males derived from mod(mdg4)+ females have a similar phenotype to y2/Y males, y2/Y; mod(mdg4)ul/+ males derived from mod(mdg4)ul/mod(mdg4)ul females have a variegated pigmentation phenotype.

The ability of various null y alleles to complement the y2 phenotype has been studied. The results suggest that where the null y allele can complement the y2 phenotype, functional wing and body cuticle enhancers located in the null y allele may be acting in trans on the promoter in the y2 allele.
Promoter causes trans-activation of y1 enhancer.
The y2 phenotype can be reproduced by transforming y- flies with a construct carrying a gypsy insert into y. gypsy insertion separates the wing and body tissue-specific enhancers from the y promoter (FBrf0046293).
