DNA or genens these are the segments of the chromosome.
Deletion: a segment of the chromosome is lost during breakage. Duplication: a segment of the chromosome is copied and inserted back into the chromosome following breakage. Inversion: a segment of the chromosome is reversed and re-inserted following breakage. Translocation: a segment of the chromosome breaks off and joins a different chromosome.
A gene is a segment of DNA that contains the instructions for making a specific protein or RNA molecule, which determines a particular trait or characteristic. Each gene is located at a specific position on a chromosome in the cell's nucleus.
The extra chromosome segment may be located immediately after the normal segment in precisely the same orientation forms the tandemWhen the gene sequence in the extra segment of a tandem in the reverse order i.e, inverted , it is known asreverse tandem duplicationIn some cases, the extra segment may be located in the same chromosome but away from the normal segment - termed as displaced duplicationThe additional chromosome segment is located in a non-homologous chromosome is translocation duplication.
A loss of a complete chromosome is called monosomy. This occurs when a cell only has one copy of a particular chromosome instead of the usual two copies.
A segment of DNA on a chromosome that controls the production of a protein is called a gene. Chromosome a cellular structure that contains DNA.
The mutation in which a segment of a chromosome is repeated is known as duplication.
Deletion: a segment of the chromosome is lost during breakage. Duplication: a segment of the chromosome is copied and inserted back into the chromosome following breakage. Inversion: a segment of the chromosome is reversed and re-inserted following breakage. Translocation: a segment of the chromosome breaks off and joins a different chromosome.
A gene is a segment of DNA that contains the instructions for making a specific protein or RNA molecule, which determines a particular trait or characteristic. Each gene is located at a specific position on a chromosome in the cell's nucleus.
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
The extra chromosome segment may be located immediately after the normal segment in precisely the same orientation forms the tandemWhen the gene sequence in the extra segment of a tandem in the reverse order i.e, inverted , it is known asreverse tandem duplicationIn some cases, the extra segment may be located in the same chromosome but away from the normal segment - termed as displaced duplicationThe additional chromosome segment is located in a non-homologous chromosome is translocation duplication.

Genes
A loss of a complete chromosome is called monosomy. This occurs when a cell only has one copy of a particular chromosome instead of the usual two copies.
There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions
An Inversion mutation is a mutation that causes a reversal in the order of a segment of a chromosome within the chromosome, or a gene.
a gene
When a segment of a chromosome breaks away and joins a non-homologous chromosome, it is called a translocation. This can lead to gene disruptions and potentially cause genetic disorders.
