Deletion of approximately 10kb that joins the 5' end (promoter, untranslated leader and 5' coding sequences) of ph-p to the 3' end of ph-d (3' coding region and untranslated sequences) and removes all sequences in between.
ph-p2/Hsc70-4195 mutant flies exhibit a higher than wild-type average number of legs with sex combs, with a statistically significant average of 4.0 legs with sex combs, compared to 2.6 in ph-p2/+ heterozygotes.
ph-d2 ph-p2 homozygotes do not show a gap in the fourth wing vein at 25 or 29oC. 100% of ph-d2 ph-p2/+ ; en54/+ flies have a gap in the fourth wing vein at 29oC. 100% of ph-d2 ph-p2/+ ; en4/+ flies have a gap in the fourth wing vein at 29oC.
The extra sex combs phenotype of ph-p2 heterozygotes is dominantly enhanced by Df(2L)esc-P2-0, Df(2L)prd1.7, Df(2L)esc10, salm1, Df(2L)H20, Df(2L)TW3, Df(2L)TW201, Df(2R)CA53, Df(2R)cn83c, Df(3L)fz-GF3b, Df(3L)fz-GS1a and Df(3L)fz-CAL5. Lethal in heterozygous combination with Df(2L)Prl.
