Explanation:
Detailed explanation-1: -Deletions occur when a chromosome breaks and some genetic material is lost. Deletions can be large or small, and can occur anywhere along a chromosome. Duplications. Duplications occur when part of a chromosome is abnormally copied (duplicated).
Detailed explanation-2: -Chromosomal Deletions Deletions involve the loss of DNA sequences. Phenotypic effects of deletions depend on the size and location of deleted sequences on the genome. For instance, deletions that span a centromere result in an acentric chromosome that will most likely be lost during cell division.
Detailed explanation-3: -In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign:
