      ash1N303mut is a dominant enhancer of eye pigment variegation observed in the E1 (combination of gypsy{}ci-E1, P{lacW}Dplac) and Pci (P{lacW}Dplac) backgrounds; no eye pigmentation silencing is observed in a P{lacW}3-76a background.

      ash1N303mut is a significant dominant suppressor of eye pigment variegation observed in the In(1)w[m4] background.

      The following transheterozygotes are lethal: ash1N303mut/Df(3L)Exel9007, ash1N303mut/ash1W790term, ash1N303mut/ash1Q893term, ash1N303mut/ash1H1873W and ash1N303mut/ash1W770mut.

      ash1N303mut/+, trxS2582a/+ and ash1N303mut/+, trxS2582b/+ double heterozygotes are viable, whereas ash1N303mut/+, trxR1578mut/+ double heterozygotes are semi-viable, as compared to controls.

      ash1N303mut/+, trxS2582a/+ double heterozygous females show a dominant enhancer of eye pigment variegation phenotype which is more severe than either single heterozygote.
