Assertion :- Translocation is a illigal crossing over
Reason : Translocation is exchange of chromosomal segments between nonhomologous chromosome

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are trur but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is Flase.
D. If both Assertion & Reason are false.

Answer

To solve the assertion-reason question, we will analyze both the assertion and the reason step by step.

### Step 1: Understanding the Assertion
The assertion states: "Translocation is an illegal crossing over."
- Translocation refers to the process where segments of chromosomes are exchanged between non-homologous chromosomes.
- In the context of genetics, "illegal" suggests that this process is not a normal or typical occurrence, unlike crossing over which occurs during meiosis.

### Step 2: Understanding the Reason
The reason states: "Translocation is the exchange of chromosomal segments between non-homologous chromosomes."
- This statement accurately describes translocation. It involves the exchange of genetic material between chromosomes that are not homologous, meaning they do not have the same structure or genetic content.

### Step 3: Evaluating the Assertion and Reason
- The assertion is true because translocation is indeed considered an "illegal" form of crossing over since it occurs between non-homologous chromosomes.
- The reason is also true as it correctly describes what translocation is.

### Step 4: Analyzing the Relationship between Assertion and Reason
- Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that the assertion is supported by the reason.

### Conclusion
Both the assertion and the reason are correct, and the reason provides a correct explanation for the assertion.

### Final Answer
Both the assertion and the reason are correct, and the reason correctly explains the assertion.
