Cytogenetics of Xenopus laevis. I. G-banding pattern of Xenopus laevis chromosomes.

Although karyotype analyses by G-band staining have been used routinely in mammals, birds and reptiles, few have been reported in amphibia. We succeeded, however, in differential chromosome staining of some chromosomes of the African clawed toad, Xenopus laevis, by using the trypsin technique.
