Q1: Which clinical manifestations would be expected for a child
who has complete trisomy of the twenty-first chromosome?
A: ANS: B
Individuals with this disease are mentally retarded, with IQs usually ranging from 25 to 70.
Q2: a. Widely spaced nipples, reduced carrying angle at the
elbow, and sparse body hair
A: The facial appearance is distinctive and exhibits a low nasal bridge, epicanthal folds
(which produce a superficially Asian appearance), protruding tongue, and flat, low-set
ears. The correct option is the only one that accurately describes the clinical
Q3: b. An IQ of 25 to 70, low nasal bridge, protruding tongue, and
flat, low-set ears
A: manifestations of the complete trisomy of the twenty-first chromosome.
Q4: c. High-pitched voice, tall stature, gynecomastia, and an IQ of
60 to 90

Q5: d. Circumoral cyanosis, edema of the feet, short stature, and
mental slowness

A: Nondisjunction during the formation of one of the parent's gametes or during early
embryonic development occurs in approximately 97% of infants born with Down
Q8: c. Maternal nondisjunction
A: syndrome. In approximately 90% to 95% of infants, the nondisjunction occurs in the
