Which of the following chromosome numbers show maximum similarity in banding pattern in man and chimpanzee?

Options

A. 1 and 2
B. 2 and 3
C. 3 and 6
D. 6 and 12

Answer

To solve the question regarding which chromosome numbers show maximum similarity in banding patterns between humans and chimpanzees, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**:
- Humans (Homo sapiens) and chimpanzees (Pan troglodytes) are closely related primates. Their genetic similarity is significant, with studies showing that humans and chimpanzees share about 98-99% of their DNA.

2. **Chromosome Analysis**:
- Both humans and chimpanzees have a specific number of chromosomes. Humans have 46 chromosomes (23 pairs), while chimpanzees have 48 chromosomes (24 pairs).

3. **Banding Patterns**:
- Chromosomes can be stained to produce a banding pattern, which helps in identifying structural similarities and differences between species.

4. **Identify Similar Chromosomes**:
- Research indicates that certain chromosomes in humans and chimpanzees exhibit similar banding patterns. In this case, chromosomes 3 and 6 have been identified as showing maximum similarity between the two species.

5. **Conclusion**:
- Based on the analysis, the chromosome numbers that show maximum similarity in banding patterns between humans and chimpanzees are **3 and 6**.

### Final Answer:
The chromosome numbers that show maximum similarity in banding pattern in man and chimpanzee are **3 and 6**.
