Baldness in man is a :-

Options

A. Autosomal character
B. Sex linked character
C. Sex limited character
D. 1 and 3 both

Answer

**Step-by-Step Solution:**

1. **Understanding Baldness in Men**: Baldness, particularly male pattern baldness, is a condition that affects hair growth and is often more pronounced in males than in females.

2. **Identifying the Genetic Basis**: The gene responsible for baldness is located on the X chromosome. Since males have one X and one Y chromosome (XY), while females have two X chromosomes (XX), this genetic trait is linked to the sex chromosomes.

3. **Analyzing the Options**:
- **Autosomal Character**: This refers to traits controlled by genes located on autosomes (non-sex chromosomes). Since baldness is linked to the X chromosome, this option is incorrect.
- **Sex-Limited Character**: This refers to traits that are expressed in one sex but not the other, even though both sexes may carry the gene. Baldness is more commonly expressed in males, making this option a strong candidate.
- **Sex-Linked Character**: This indicates that the gene is located on a sex chromosome. Baldness is indeed linked to the X chromosome, but the question asks for the nature of the expression of the trait.

4. **Conclusion**: Given that baldness is predominantly observed in males due to the influence of male hormones (androgens) and the fact that the gene is located on the X chromosome, the most accurate description of baldness in men is that it is a **sex-limited character**.

**Final Answer**: Baldness in man is a **sex-limited character**.
