Cytological Observations on the Filamentous Organization of Salivary Chromosomes of Drosophila parasaltans (Saltans Group)

Abstract

Cytological observations on anomalous salivary chromosomes of D. parasaltans showed some features presented to discuss their filamentous structure.
The abnomally large size plus the loose structure of such chromosomes allowed us to base our observations on pictures taken through the optical microscope.
