Zusammenfassung
Die Analyse der mitotischen Chromosomen beiSciurus carolinensis, S. niger undS. aberti ergibt die diploide Zahl 40 und gleichartige Karyotypen.S. griseus, 2n 40, hat einzigeY Chromosomen und sekundäre Konstriktionen in 4 Autosomen.Glaucomys sabrinus undG. volans, 2n 48, zeigten kleinere Unterschiede der Karyotypen. Taxonomische Bezeichnungen vonSciurus, Glaucomys undTamiasciurus werden erörtert.
