Duplication
Translocation
Inversion
Crossing over
A set of genes at different loci on the same chromosome tend to act as a single pair of genes in meiosis instead of undergoing independent assortment. The chromosome translocation is caused by the rearrangement of parts between nonhomologous chromosomes. Hence in translocation, there is a movement of a chromosome segment from one linkage group to another. Hence, correct option is A.
