Removing amniotic fluid to study human chromosomes is called?

The process of extracting amniotic fluid from the amniotic sac surrounding a developing fetus to investigate human chromosomes is known as amniocentesis. Performed typically between 15-20 weeks of gestation, amniocentesis allows for prenatal genetic screening, diagnosis of genetic disorders, and determination of fetal sex, among other purposes. Through analysis of fetal cells present in the amniotic fluid, genetic abnormalities can be identified, providing crucial information to prospective parents and facilitating appropriate medical decisions.
