Chromosomal Rearrangement

Chromosomal rearrangements are changes in the arrangement of an organism's chromosomes; this can be either the addition or subtraction of genes from a chromosome or a change in the physical structure of the chromosome. These changes are significant to the organism's development and regulation of its genes, as well as its ability to reproduce. They can be beneficial, as they can allow for the adaptation to new environments, or they can be disruptive, resulting in birth defects and genetic disorders. Chromosomal rearrangements are often used in genetic research and to diagnose different genetic disorders. They can also be studied in order to better understand the regulation of genes within organisms.
