通过单代杂种发育不全传代而诱变的黑腹果蝇野生型染色体与通过互惠、非发育不育杂交传递的相同染色体进行了比较。使用平衡器染色体平衡技术在群体笼中检查了纯合条件下染色体的适应性。结果表明，在没有致命或可见突变的染色体中，超过 50% 的染色体的适应性出现了可测量的下降。据估计，下降幅度在 10% 至 20% 之间。
Wild-type chromosomes of D. melanogaster mutagenized by passage through a single generation of hybrid dysgenesis have been compared against identical chromosomes passed through a reciprocal, non-dysgenic cross. Fitness of the chromosome in homozygous condition has been examined in population cages using the technique of balancer chromosome equilibration. The results indicate that amongst chromosomes with no lethal or visible mutation, more than 50% have suffered a measurable decline in fitness. The magnitude of this decline is estimated to be in the range 10–20%.
