Which is gentically transmitted trait?

Options

A. Haemophilia
B. Muscular dystrophy
C. Colour blindess
D. All the above

Answer

To determine which of the listed traits is genetically transmitted, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Genetic Transmission**:
- Genetic transmission refers to the passing of traits or disorders from parents to offspring through genes.

2. **Analyzing Option 1: Hemophilia**:
- Hemophilia is an X-linked recessive disorder. This means that the gene responsible for hemophilia is located on the X chromosome. Since it is inherited through the X chromosome, it is genetically transmitted.

3. **Analyzing Option 2: Muscular Dystrophy**:
- Muscular dystrophy is also an X-linked disorder. The gene that causes muscular dystrophy is located on the X chromosome, which means it can also be passed down genetically from parents to children.

4. **Analyzing Option 3: Color Blindness**:
- Color blindness is another X-linked recessive disorder. The genes responsible for color vision are located on the X chromosome, making color blindness a genetically transmitted trait as well.

5. **Conclusion**:
- Since all three options (hemophilia, muscular dystrophy, and color blindness) are X-linked disorders that can be inherited, the correct answer is option 4: **All the above**.

### Final Answer:
The genetically transmitted traits from the options provided are: **Option 4: All the above**.
