The exchange of segments of two non-homologous chromosomes is termed as translocation
In genetics, a chromosome translocation is a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes. A gene fusion may be created when the translocation joins two otherwise-separated genes, it is detected on cytogenetics or a karyotype of affected cells.

lvurself: could uh pls tell me than how it differs from crossing over

GNM: Crossing over is an exchange of genetic material between homologous chromosomes that occurs during prophase I of meiosis, the formation of gametes.Translocation is a genetic abnormality involving the exchange of fragments of genes between non-homologous chromosomes.

GNM: Translocation of chromosomes is mutations; crossing over is not. The reason for this distinction is that translocation results in a change in the genetic information, while crossing over simply swaps genetic material between “like” chromosomes unchanged.

lvurself: thanks for making my concepts clear..R uhh doing mbbs?

GNM: Nope in class 12

lvurself: ohhkk
