Resumo

A translocated chromosome involving chromosome 9 and a B chromosome was used. The breakpoint in chromosome 9 was close to the tip, the deficient fragment including only one or two chromomeres, while the break in the B chromosome was near the junction of the euchromatin and the proximal heterochromatin of the long arm.
