Reciprocal translocation

Reciprocal translocation
A type of chromosome rearrangement involving the exchange of chromosome segments between two chromosomes that do not belong to the same pair of chromosomes. A specific reciprocal translocation might, for example, involve the swap of material between chromosomes 1 and 19.
