Abstract
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.
