title: Satellite DNA in the three C-bands of an unusual mouse marker chromosome. A model of chromosomal evolution.
abstract: A marker chromosome in the stemline of a new murine cell line is described on the basis of different stainings and in situ hybridization. The marker was characterized originally by three C-bands, one from each centromeric region of the three chromosomes constituting the marker. In the course of stemline evolution, two of the C-bands have been lost and the marker has developed into a monocentric chromosome, phenotypically and functionally normal.
