Identify the worng statement

Answer

To identify the wrong statement from the provided options, let's analyze each statement step by step:

### Step 1: Analyze the First Statement
**Statement:** Human males have one sex chromosome much shorter than the other.

- In humans, males have one X and one Y chromosome (XY).
- The Y chromosome is indeed shorter than the X chromosome.
- **Conclusion:** This statement is true.

### Step 2: Analyze the Second Statement
**Statement:** In domesticated fowl, the sex of progeny depends upon the type of sperm that fertilizes the egg.

- In domesticated fowl (birds), the sex determination system is ZW for females and ZZ for males.
- The female (ZW) is heterogametic, meaning she has two different sex chromosomes.
- The male (ZZ) is homogametic, meaning he has two identical sex chromosomes.
- The sex of the progeny is determined by the type of egg (ZW or ZZ) produced by the female, not the sperm.
- **Conclusion:** This statement is false.

### Step 3: Analyze the Third Statement
**Statement:** In male grasshoppers, 50% of the sperms have no sex chromosome.

- Grasshoppers have an XO sex determination system.
- Males have one X chromosome and no second sex chromosome (XO).
- Therefore, 50% of the sperm produced by males will carry the X chromosome, and 50% will carry no sex chromosome at all.
- **Conclusion:** This statement is true.

### Final Conclusion
The wrong statement among the given options is the second statement regarding domesticated fowl.
