Amniotic Fluid Analysis for Foetal Sex Determination

Understanding how foetal sex can be determined through examining cells from the amniotic fluid is crucial in prenatal diagnosis. Here's a detailed explanation:

Barr bodies
- Barr bodies are condensed, inactive X chromosomes found in the nuclei of female somatic cells.
- By examining the presence of Barr bodies in cells from the amniotic fluid, the sex of the foetus can be determined.
- A female foetus would have Barr bodies indicating the presence of two X chromosomes, while a male foetus would lack Barr bodies.

Therefore, the correct option for determining foetal sex by examining cells from the amniotic fluid is option 'A' - Barr bodies. This method is reliable and commonly used in prenatal testing to determine the sex of the foetus.
