Detailed explanation-1: -A deletion, as related to genomics, is a type of mutation that involves the loss of one or more nucleotides from a segment of DNA. A deletion can involve the loss of any number of nucleotides, from a single nucleotide to an entire piece of a chromosome.

Detailed explanation-2: -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-3: -Another example of a deletion mutation-related disorder is Turner syndrome, where there is a deletion of the entirety of the X chromosome. Turner syndrome patients are females that have a variety of developmental and medical complications such as defective ovaries, heart, and learning disabilities.

Detailed explanation-4: -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-5: -Cri du chat syndrome is a chromosomal disorder caused by a partial deletion (monosomy) of a varying length of the short arm (p) of chromosome 5. Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual.
