Practice Question
Down Syndrome is caused by which additional chromosome?
Answer Choices:
Correct Answer:
21
Rationale:
🟠 Down syndrome results from an extra copy of chromosome 21, known as trisomy 21.
🟠 This genetic abnormality leads to typical features and developmental delays associated with Down syndrome.
🟠 Chromosomes 19, 20, and 22 are not linked to Down syndrome; trisomy of these chromosomes leads to other disorders or may not be compatible with life.
🟠 Early diagnosis through genetic testing allows for appropriate support and family counseling.
🟠 Chromosome 21 is always associated with classic Down syndrome findings.
