Definition
Chromosomal translocation in which crossing over between two non-homologous chromosomes leads to each carrying genetic material from the other.

Note
If the exchange is equal (i.e., no genetic material is missing) it is called a balanced translocation, and may be without severe consequences for the developing embryo. If extra or missing genetic material results from the process, it is called an unbalanced translocation, and the consequences are often more harmful.
