chromosomal mutation

A chromosomal mutation is a change in the structure or number of chromosomes, which are the DNA-carrying units in our cells. These mutations can occur due to errors during cell division or exposure to certain chemicals or radiation. They may involve parts of a chromosome being deleted, duplicated, flipped, or swapped, or changes in the overall number of chromosomes. Such mutations can affect gene function and may lead to genetic disorders or new traits. While some are harmless, others can have significant health implications depending on the nature and extent of the change.
