Transfer of a part of chromosome or set of genes to a non-homologous chromosome is called ___________.

Options

A. deletion
B. duplication
C. inversion
D. translocation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the transfer of a part of a chromosome or a set of genes to a non-homologous chromosome.

2. **Identifying Key Terms**: The key terms in the question are "transfer," "part of chromosome," "set of genes," and "non-homologous chromosome." This indicates a specific type of genetic alteration.

3. **Reviewing Types of Chromosomal Mutations**: There are several types of chromosomal mutations, including deletion, duplication, inversion, and translocation. Each of these has a distinct definition:
- **Deletion**: Removal of a segment of a chromosome.
- **Duplication**: A segment of a chromosome is duplicated, resulting in extra genetic material.
- **Inversion**: A segment of a chromosome is reversed end to end.
- **Translocation**: A segment of a chromosome is moved to a different, non-homologous chromosome.

4. **Focusing on Translocation**: The definition of translocation fits the question perfectly, as it involves the transfer of a chromosome segment to a non-homologous chromosome.

5. **Conclusion**: Therefore, the answer to the question is "translocation."

**Final Answer**: Transfer of a part of chromosome or set of genes to a non-homologous chromosome is called **translocation**.
