reciprocal translocation

https://doi.org/10.1351/goldbook.11166

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.
