Body colour: pigmentation score (where 1 = null/nearly null, 5 = wild type/nearly wild type): hemizygote: 1 (wing), 1 (body), homozygote: 1 (wing), 1 (body), ytata-1/y82f29 : 2 (wing), 1-2 (body), ytata-1/y2 : 3 (wing), 2-3 (body), ytata-1/y62a : 2 (wing), 4 (body), ytata-1/y2374 : 3 (wing), 2-3 (body).
Body colour: homozygous and hemizygous flies show fully mutant pigmentation in all cuticular structures.
