We can have inversion, we can have deletion, we can have duplication and translocation. So in either case, we have a segment of that chromosome breaking off. And in inversion, once that chromosome segment breaks off, it flips, it reverses its orientation and reinserts back into that original chromosome. In deletion, we have that broken off detached chromosome segment, basically moves away and never reattaches onto that particular original chromosome. In the case of duplication, we're dealing with a homologous pair of chromosomes. And so we have chromosome number one, and it's Homologous chromosome number two.
