The correct Answer is:
The arrangement of chromosomes based on their shape and size is called a **Karyotype**. ### Step-by-Step Solution: 1. **Understanding Chromosomes**: Chromosomes are structures within cells that contain DNA. They come in pairs and can vary in size and shape. 2. **Chromosome Arrangement**: When scientists study chromosomes, they often arrange them in a specific order based on their characteristics, such as size and shape. 3. **Identifying the Term**: The term used for this arrangement is crucial. The options given are: - Ideogram - Karyotype - Chromatid - Mutation 4. **Defining the Terms**: - **Karyotype**: This is the correct term for the arrangement of chromosomes based on size and shape. It shows all the chromosomes in an organism, typically in pairs. - **Ideogram**: This is a diagrammatic representation of a karyotype, showing the chromosomes in a simplified form. - **Chromatid**: This refers to one half of a duplicated chromosome. - **Mutation**: This refers to a change in the DNA sequence. 5. **Conclusion**: Based on the definitions and the context of the question, the correct answer is **Karyotype**.
