And here we have a deletion, because this segment that broke off does not actually return to this particular chromosome. So when duplication takes place, deletion also takes place, as we see in this particular example. So if a segment of DNA breaks off and attaches onto a homologous chromosome, because that homologous chromosome carries those same types of genes, we say that we have a chromosomal duplication take place. And finally, let's examine translocation. So translocation is the process by which a segment of that chromosome breaks off and moves onto and attaches onto a non homologous chromosome. So to see what we mean, let's take a look at the following diagram.
