Oblique wing phenotype (o). Thoracic vortex phenotype (v). dpolvM/+ showed oblique truncated wings in up to 90% of flies in maximally selected lines. RK2.
Altenburg and Muller established that temperature and modifier genes affect a major gene at 2-13.0. Later tests with dpov1, dpv, dpo, and other alleles established similarity to dpolv.
