Males always inherit these traits from the female parents

Options

A. Y-linked
B. X-linked
C. X and Y - linked
D. XY-linked

Answer

To solve the question "Males always inherit these traits from the female parents," we need to analyze the inheritance of sex-linked traits, particularly focusing on the X and Y chromosomes.

### Step-by-Step Solution:

1. **Understanding Male Chromosomes**:
- Males have one X and one Y chromosome (XY). The X chromosome is inherited from the mother, while the Y chromosome is inherited from the father.

2. **Identifying Maternal Inheritance**:
- Since the mother has two X chromosomes (XX), she can only pass on an X chromosome to her offspring. Therefore, any traits linked to the X chromosome will be inherited from the mother.

3. **Examining the Options**:
- The options given are:
- Y-linked
- X-linked
- X and Y-linked
- X-linked (repeated)
- Since males inherit their Y chromosome from their fathers, Y-linked traits cannot be inherited from the mother.

4. **Determining the Correct Option**:
- The only traits that males inherit from their female parents are those linked to the X chromosome. Therefore, the correct answer is "X-linked".

5. **Conclusion**:
- Males always inherit X-linked traits from their female parents.

### Final Answer:
- The correct option is **X-linked**.
