What is the cause and effect of inversion, duplication and deletion to a chromosome?

Rearrangement of chromosomes includes many varieties of events: deletions, inversions, duplications, and translocations. Each of these events can be because of the DNA double helices breakage in the genome at two different locations, followed by reconnecting of the chromosomes before they were broken. Rearrangements could be induced artificially by using iodizing radiation, consistent with the chromosomal origin rearrangements by breakage. In this kind of radiation whereby x-rays and gamma rays are mostly used, is highly energetic and numerous double-stranded are broken in DNA.
