The movement of a gene from one linkage group to another is calledTranslocation: a chromosome segment separates and joins a non-homologous chromosome, so genes move to another linkage group.
Inversion reverses the gene order of a segment by $180^\circ$; duplication repeats a segment; crossing over exchanges segments between homologous chromosomes.
