 | | Representatives were karyotyped from the superorders: Galeomorphii (4 orders), Squalomorphii (3 orders), Squatinomorphii (1 genus), and Batoidea (4 or 5 orders). |
 | | The 36 elasmobranch species karyotyped by this method, together with 20 species using colchine, represent ~4.3% of living chondrichthyans. |
 | | A fusion model (rather than fission or modal models) best explained the data obtained for the galeomorphs and batoids studied and explains karyotypic change in other superorders. |
