Chracteristic diploid chromosome complement of an organism is called

Options

A. Idiogram
B. Linkage group
C. Karyotype
D. None

Answer

To solve the question "Characteristic diploid chromosome complement of an organism is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Diploid":**
- The term "diploid" refers to a cell or organism that has two complete sets of chromosomes, one from each parent. This is denoted as "2n," where "n" represents the number of chromosomes in a single set.

2. **Identify the Key Concept:**
- The question is asking for a specific term that describes the complete set of diploid chromosomes in an organism.

3. **Evaluate the Options:**
- **Option A: Ideogram** - An ideogram is a graphical representation of the chromosomes, not the chromosome complement itself. Therefore, this option is incorrect.
- **Option B: Linkage Group** - A linkage group refers to a group of genes that tend to be inherited together due to their proximity on the chromosome. This does not represent the complete diploid chromosome set, so this option is also incorrect.
- **Option C: Karyotype** - A karyotype is the complete set of chromosomes in an organism, organized and classified. It specifically refers to the diploid chromosome complement, making this option correct.

4. **Conclusion:**
- The characteristic diploid chromosome complement of an organism is called a **karyotype**.

### Final Answer:
The correct answer is **karyotype**.
