Each of these mutations can cause a variety of different diseases and conditions. Read on to learn what these mutations are and what disorders they can cause. slide 1 of 8. The causes of chromosomes mutation occur when there is any change in the arrangement or structure of the chromosomes.These mutations occur most often during meiosis during the stage when crossing over occurs. There are several different mutation types that result in chromosomal structure change.This change in structure leads to serious changes in an organisms' phenotype and genotype. If essential parts of the DNA are affected by chromosomal mutations, a foetus can be aborted prior to birth without the mother's control.ach of these mutations can cause a variety of different diseases and conditions.
