ABSTRACT

Two Uruguayan populations of Drosophila nebulosa were studied for chromosomal polymorphism of paracentric inversions. A new inversion on the second chromosome, named IIR A, was found. The Uruguayan populations and the closest studied populations of D. nebulosa, from Porto Alegre, Southern Brazil, were compared. A photomap of the polytene chromosomes of this species was constructed.

Keywords: photomap; Drosophila nebulosa; Sturtevant; new inversion.
