Detailed explanation-1: -Deletions. Deletions occur when a chromosome breaks and some genetic material is lost.
Detailed explanation-2: -A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. A DNA sequence is a chain of many smaller molecules called nucleotides.
Detailed explanation-3: -(deh-LEE-shun) A type of genetic change that involves the absence of a segment of DNA. It may be as small as a single base but can vary significantly in size.
Detailed explanation-4: -Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
Detailed explanation-5: -The four main types of structural chromosomal aberrations are deletion, duplication, inversion, and translocation.
