Summary Introduction
Introduction:
The chromosomes are arranged in a sequenced pattern, which enables the effective transfer of genetic material. Any alteration in the placement of the chromosomes leads to the mutations, such as deletions, duplications, inversions, and translocations. These mutations may have harmful effects on the organism.
