利用转座元件标记的等基因重组体定位了果蝇2号染色体翼形指数的遗传效应。至少有10个加性效应很小的基因均匀分布在染色体上。存在许多交互作用，纯合子重组体的净效应很小，对表型变异的影响很小。杂合染色体片段几乎没有显性。多效性对腿部形状的影响很小。乍一看，翅膀形状基因形成了一个相当同质的类别，但某些复杂性仍未解决。
Genetic effects on an index of wing shape on chromosome 2 of Drosophila melanogaster were mapped using isogenic recombinants with transposable element markers. At least 10 genes with small additive effects are dispersed evenly along the chromosome. Many interactions exist, with only small net effects in homozygous recombinants and little effect on phenotypic variance. Heterozygous chromosome segments show almost no dominance. Pleiotropic effects on leg shape are only minor. At first view, wing shape genes form a rather homogeneous class, but certain complexities remain unresolved.
