Answer

### Step-by-Step Solution:

1. **Understanding Amniocentesis**: Amniocentesis is a medical procedure used during pregnancy to obtain amniotic fluid, which contains fetal cells. This fluid can be analyzed for genetic and chromosomal disorders.

2. **Evaluating the Statements**:
- **Statement 1**: "It is used for prenatal sex determination."
- This statement is **correct**. Amniocentesis can determine the sex of the fetus, although this practice is restricted in many places to prevent gender-based abortions.

- **Statement 2**: "It can be used for detection of syndrome."
- This statement is also **correct**. Amniocentesis is commonly used to detect chromosomal syndromes such as Down syndrome and Turner syndrome.

- **Statement 3**: "It can be used for the detection of cleft palate."
- This statement is **incorrect**. Amniocentesis cannot be used to detect cleft palate, as this condition is related to the physical structure of the face and is typically diagnosed through imaging techniques like ultrasound.

- **Statement 4**: "It is usually done when a woman is between 14 to 16 weeks pregnant."
- This statement is **correct**. Amniocentesis is typically performed between the 14th and 16th weeks of pregnancy.

3. **Conclusion**: The incorrect statement regarding amniocentesis is **Statement 3**: "It can be used for the detection of cleft palate."

### Final Answer:
The incorrect statement in the context of amniocentesis is: **"It can be used for the detection of cleft palate."**
