Geographic patterns of inversion polymorphism in the second chromosome of the cactophilic drosophila buzzatii from Northeastern Argentina

Mostrar todas las versiones(3)

The inversion polymorphisms of the cactophilic Drosophila buzzatti Patterson and Wheeler (Diptera: Drosophilidae) were studied in new areas of its distribution in Argentina. A total of thirty-eight natural populations, including 29 from previous studies, were analyzed using multiple regression analy...
