Summary
Specimens of the green toad,Bufo viridis, from Morocco to Kirgizistan, have identical DNA amounts per erythrocyte nucleus. 1 specimen from Kirgizistan is a tetraploid. Of 3 closely related species,B. calamita andB. brongersmai have about the same DNA amount asB. viridis, whileB. latastii from Afghanistan has 36% more DNA per nucleus.
