The exchange of one part of a chromosome to the other part of some or another chromosome is called
Or
The movement of gene from one linkage group to another is called

Options

A. duplication
B. translocation
C. crossing over
D. inversion

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the exchange of parts of chromosomes or the movement of genes from one linkage group to another.

2. **Identifying Key Terms**:
- "Exchange of one part of a chromosome to the other part of some or another chromosome"
- "Movement of gene from one linkage group to another"

3. **Analyzing the Options**:
- **Duplication**: This refers to the production of one or more copies of a gene or chromosome segment. It does not involve exchange or movement between chromosomes.
- **Translocation**: This is the movement of a chromosomal segment from one position to another, which can involve different chromosomes. This fits the description provided in the question.
- **Crossing Over**: This involves the exchange of genetic material between homologous chromosomes during meiosis, but it does not typically refer to movement between different linkage groups.
- **Inversion**: This is a rearrangement of a chromosome segment where the segment is reversed. It does not involve exchange between different chromosomes.

4. **Selecting the Correct Answer**: Based on the definitions and the context of the question, the correct answer is **Translocation**. This is because translocation specifically describes the movement of a chromosomal segment from one chromosome to another, which aligns with the question's requirements.

5. **Conclusion**: The exchange of one part of a chromosome to the other part of some or another chromosome, or the movement of a gene from one linkage group to another, is called **Translocation**.
