Interpretation by Maurizio Gatti: These cells are basically tetraploid but display an elevated karyotypic variability. They usually exhibit four third chromosomes and four second chromosomes but, in some cells, one of the third chromosomes is split into two halves, due to a translocation with either the X or the fourth chromosome. The X chromosomes vary in number (from four to two) and morphology; in some cells, there is a characteristic exchange between two X chromosomes (cells 3 and 4), which results in an apparently dicentric element. However, it is not a dicentric chromosome in that sister chromatid attachment at its non-fluorescent tip is mediated by the presence of heterochromatin and not of a centromere. The dot chromosomes vary in number like the X chromosomes, ranging from 2 to 5.
