Dp(1;4)mg hyperploids have reduced viability and homozygotes having an otherwise normal genotype are lethal. Homozygotes survive if the fly is heterozygous, homozygous or hemizygous for deficiencies in the z-w region. Viability of Dp(1;4)mg hyperploids improves at lower temperatures and in X0 males, suggesting position-effect-variegation of the transposed genes (Robbins).
