Translocation is the transfer of a portion of one chromosome to another non-homologous chromosome. When the translocation involves a large segment or whole chromosome, it is called a balanced translocation, but when only a small segment is involved, it is called an unbalanced translocation. In this case, as the question states that a piece of one chromosome has translocated to a non-homologous chromosome, it is most likely an unbalanced translocation.
