title: G and C banding show structural differences between the Z and W chromosomes in the frog Buergeria buergeri.
abstract: G and C banding studies were made on cultured blood cells of matured male and female Buergeria (B.) buergeri frogs. The Z is subtelocentric and the W is submetacentric. There is a satellite near the end of the long arm of the Z. Constitutive heterochromatin is seen near the proximal and distal portions of the long arms of both Z and W. A single heavily stained G band is seen in the short arm of Z, while one or two heavily stained G bands are observed in the short arm of W. The Z may have originated through a process, in the course of which parts of W have been translocated to Z.
