Abbreviations: N, number of cells analyzed; n, haploid chromosome arm complement.
Aneuploidy rates (NDJ%) are estimated from metaphase II plates (MII), and sex-chromosome (X/Y%) as well as autosome pair dissociation (Other%) from metaphase I plates (MI). Dissociations are indicated by a slash between the chromosomal elements, whereas XY records cells with paired sex chromosomes. For details on segregation type, see text. The asterisk indicates the wild hybrid. Mean values are provided with standard error. No cells showing a 4:0 segregation pattern were observed.
