Chromosomal polymorphism and wing size (as a measure of body size) were analysed simultaneously in two samples of Drosophila subobscura from Barcelona, Spain. The very rich chromosomal polymorphism of this species makes it difficult to detect the relationship of this polymorphism with any phenotypical character. However, a positive significant regression of wing size on the percentage of the autosome length with standard arrangement was found. Furthermore, for each polymorphic chromosome, except for the J chromosome, an association between the most frequent arrangements and wing size was observed. This trend, which was the same in the two samples, was that expected according to the latitudinal clines of both characters.
在来自西班牙巴塞罗那的两果蝇亚暗果蝇样本中，同时分析了染色体多态性和翅大小（作为体型的度量）。该物种极其丰富的染色体多态性使得难以检测这种多态性与任何表型特征之间的关系。然而，发现翅大小与具有标准排列的常染色体长度百分比之间存在显著的正回归。此外，对于每个多态染色体，除了J染色体外，观察到最常见排列与翅大小之间存在关联。这一趋势在两个样本中是相同的，是根据这两个特征的纬度梯度所预期的。
