Genes
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.
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.
A chromosome.A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.For apex it's "A piece of a chromosome."
Deletions are a loss of all or part of a chromosome. Duplications produce extra copies of parts of a chromosome. Inversions reverse the direction of parts of a chromosome. Translocations occur when part of one chromosome breaks off and attaches to another.
The three chromosomal aberrations - deletion, duplication, and inversion - are different in terms of the changes they cause in the chromosome structure. Deletion involves the loss of a segment of the chromosome, duplication results in the presence of extra copies of a segment, and inversion entails the reversal of a segment within the chromosome. These aberrations are similar in that they can all lead to genetic disorders or abnormalities due to the changes in the chromosome structure they cause.
DNA or genens these are the segments of the chromosome.
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.
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.
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.
Just a DNA strand
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.

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.
This is known as a chromosomal duplication, which involves the replication of a segment of a chromosome resulting in an extra copy. Duplication can lead to genetic disorders or variations in an individual's traits.
