Nonreciprocal translocation

In genetics, a nonreciprocal translocation is a chromosome abnormality referring to the one-way exchange of a chromosomal segment from a non-homologous chromosome to another. It is one type of chromosomal translocation, along with reciprocal (non-Robertsonian) translocation. This type of chromosomal rearrangement involves the movement of one chromosomal segment from its original locus to a locus on a non-homologous chromosome. Unlike reciprocal translocation, nonreciprocal translocation does not involve the equal exchange of chromosomal segments between two chromosomes. Rather it is a one-way transfer, rather than two-way exchange, of chromosomal segments between two non-homologous chromosomes.
