Talk about structural chromosome mutations

Variation in its composition, do not result from meiotic non-disjunction but from breakage followed by reconstitution and ligation of substantial portions of chromosomes, and rearrangement in which a chromosome segment is inverted and transferred to another chromosome making one merged chromosome, exchange and transfer is called translocation, They can be balanced or unbalanced depending on the gain or loss of genetic constitution of chromosome, Balanced are translocations and inversions, unbalanced are a gain or loss of constitution, translocations, deletion insertions duplications and rings.
