Verified Answer
In the following question, a statement of Assertion(A) is given follow...
Chromosomal aberrations are disruptions in the normal chromosomal content of a cell, and are a major cause of genetic conditions in humans, such as Down syndrome. Strucural changes are caused by break in the chromosome or chromatid and can be of following types: (i) deficiency, involves loss of a part of chromosome, (ii) duplication, involves addition of a part of chromosome, (iii) inversion involves a reverse order of the genes in a part of chromosome and (iv) translocation, involves exchange of segments between non-homologous chromosomes.

In the following question, a statement of Assertion(A) is given follow...
Assertion(A): Chromosomal aberrations are caused by a break in the chromosome or its chromatid.
Reason(R): Duplication, deficiency, transversion, and translocations are the result of chromosomal aberrations.
The given assertion states that chromosomal aberrations are caused by a break in the chromosome or its chromatid. Chromosomal aberrations refer to structural changes that occur in the chromosomes. These changes can affect the number or structure of chromosomes, leading to abnormalities in genetic material.
The reason provided states that duplication, deficiency, transversion, and translocations are the result of chromosomal aberrations. Let's discuss each of these terms in detail to understand their association with chromosomal aberrations:
1. Duplication: Duplication is a chromosomal aberration that occurs when a segment of chromosome is repeated. This can lead to an increase in the dosage of specific genes, potentially causing genetic disorders.
2. Deficiency: Deficiency, also known as deletion, is a chromosomal aberration where a segment of chromosome is missing. This can result in the loss of specific genes, leading to various genetic disorders.
3. Transversion: Transversion refers to the exchange of genetic material between non-homologous chromosomes. This can occur due to the breakage and rejoining of chromosomes at different locations. Transversions can cause genetic abnormalities and are often associated with cancer.
4. Translocation: Translocation is a chromosomal aberration where a segment of one chromosome is transferred to another non-homologous chromosome. This can result in the rearrangement of genetic material and can have significant consequences on gene expression and function.
Conclusion: Both the assertion and reason are true. Chromosomal aberrations are indeed caused by breaks in the chromosome or its chromatid. Furthermore, duplication, deficiency, transversion, and translocations are types of chromosomal aberrations that can occur as a result of these breaks. However, the reason provided does not directly explain the assertion. It only lists some examples of chromosomal aberrations without providing an explanation for the cause of breaks in the chromosome or its chromatid. Therefore, the correct answer is option B: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
Reason(R): Duplication, deficiency, transversion, and translocations are the result of chromosomal aberrations.
