Amniocentesis is a technique to

Options

A. Determine any disease in heart
B. Determine any hereditary disease in the embryo
C. Know about the disease of brain
D. Grow cell on culture medium

Answer

### Step-by-Step Solution:

1. **Understanding Amniocentesis**:
- Amniocentesis is a medical procedure used during pregnancy. It involves taking a sample of amniotic fluid, which surrounds the fetus in the womb.

2. **Purpose of Amniocentesis**:
- The primary purpose of this technique is to analyze the genetic material of the fetus. This can help in identifying any genetic disorders or abnormalities.

3. **How Amniocentesis Works**:
- During the procedure, a thin needle is inserted through the abdominal wall into the uterus to extract a small amount of amniotic fluid. This fluid contains fetal cells that can be analyzed.

4. **Analyzing the Sample**:
- The extracted amniotic fluid is examined for chromosomal patterns and other biochemical markers. This analysis can reveal information about genetic disorders, such as Down syndrome, cystic fibrosis, and other hereditary diseases.

5. **Conclusion**:
- Based on the information gathered, amniocentesis is primarily used to determine hereditary diseases in the embryo. Therefore, the correct answer to the question is option B: "determine any hereditary disease in the embryo."
