What is partial tandem duplication?
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.
Describe four types of mutation resulting from the breakage of 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.
What is a segment of base pairsin a chromosome?
A segment of base pairs in a chromosome refers to a specific sequence of nucleotides that make up part of the DNA molecule. These segments can vary in length and may represent genes, regulatory elements, or non-coding regions. The arrangement of these base pairs encodes genetic information critical for the development, functioning, and reproduction of an organism. Each segment plays a role in the overall genetic blueprint contained within the chromosome.
A segment of chromosome responsible for a particular characteristic?
DNA or genens these are the segments of the chromosome.
What is it called when extra copies of part of a chromosome are made?
It is called gene duplication when extra copies of a gene or segment of DNA are created within a chromosome. This process can lead to genetic variation and the emergence of new gene functions.
The type of mutation in which a chromosome segment breaks away and recombines in reverse order is called?
inversion
What is an mutation?
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.

What are the four types of chromosomal mutations?
There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions

The difference between deletion duplication inversion and translocation?
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.
How are the three chromosomal aberrations different from each other how are they similar?
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.
4 chromosome mutations?
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.

What is the shorter segment of a chromosome?
Just a DNA strand
What is it called when extra copies of part of a chromosome are made?
It is called gene duplication when extra copies of a gene or segment of DNA are created within a chromosome. This process can lead to genetic variation and the emergence of new gene functions.
