Word Origin and History for translocation
Online Etymology Dictionary, © 2010 Douglas Harper
- Transposition of two segments between nonhomologous chromosomes as a result of abnormal breakage and refusion of reciprocal segments.

- A chromosomal aberration in which a chromosomal segment changes position, usually moving from one chromosome to a different, nonhomologous chromosome. In one type of Down Syndrome, for example, translocation of a large segment of chromosome 21 to another chromosome results in an individual who has the genetic equivalent of three chromosomes 21 and thus has the phenotype of Down syndrome but who has a normal total number of chromosomes. A translocation within a given chromosome is called a shift.
