Question

Amniocentesis is a prenatal diagnostic test, which can also determine whether an unborn child will have __________ or not.
A. Obesity
B. Diabetes
C. Down’s syndrome
D. All of the above

Answer 1

Hint:
In genetic amniocentesis, a sample of amniotic fluid is taken, and cells are examined for DNA which will be used to diagnose disorders like Down syndrome. Another screening test that exposed a high risk of the illness may have come after this. A fetal infection was identified. An amniocentesis may be a test that may be recommended for you during pregnancy to determine whether your unborn child has a chromosomal or genetic disorder like Down syndrome, Edwards syndrome, or Patau's syndrome.

Complete answer:
According to estimates, 98 to 99 out of each 100 women who have an amniocentesis will receive a conclusive result. However, it can't test for each condition, and during a few instances, a convincing conclusion isn't achievable. Your doctor might advise you to possess amniocentesis as a prenatal procedure throughout your pregnancy. The test looks for birth problems within the fetus, including mongolism, CF, and rachischisis. The outcomes are often normal. An amniocentesis is completed between 16 and 20 weeks of pregnancy. The correct answer is: Down syndrome

Option ‘C’ is correct

Note:
An extra chromosome causes the disorder known as Down syndrome. Within the body, chromosomes are discrete packages of genes. They control how a baby's body develops during pregnancy and after birth, determining how it'll look and work. A newborn typically has 46 chromosomes. One among these chromosomes, chromosome 21, has an additional copy in infants with Down syndrome. Trisomy is the medical word for having an extra copy of a chromosome. Mongolism is another term used to describe Down syndrome. The newborn may experience difficulties with their mental and physical development as a result of this additional copy, which alters how their body and brain grow.
