Chromosomal figs (a–d) and karyotypes (e–h) obtained from specimens belonging to clones Mo1 (a, e) e Mo2 (b, f), Mo3 (c, g) and Mo4 (d, h). Simultaneous in situ hybridization with the histone (in blue) and subtelomeric DNA probes (in green) (i–j) revealed in both clones Mo3 (i) and Mo4 (j) that the A1–A3 translocation involved the autosome 1 telomere close to the histone probe. Arrows indicate X chromosomes; asterisks indicate rearranged autosomes. Bar = 10 mm.
