Table 4. Knowledge Measures (Total N = 112).

Measure	n (%)
Common structural genetic variation (changes in the human genome, such as deletions, duplications and large-scale copy- number variants) is important in health and disease. (n=108)
True	82 (76%)
False	4 (4%)
Don't Know	22 (20%)
All the genetic variation in an individual can be attributed either to spontaneous (i.e., de novo) or inherited changes in the human genome. (n=108)
True	70 (65%)
False	13 (12%)
Don't Know	25 (23%)
The variation in the human genome includes both disease-causing gene variants and variants that have no effect on health and disease. (n=109)
True	58 (53%)
False	25 (23%)
Don't Know	26 (24%)
The DNA sequences of two randomly selected healthy individuals of the same sex are 90-95% identical. (n=108)
True	24 (22%)
False	42 (39%)
Don't Know	42 (39%)
Most common diseases such as diabetes and heart disease are caused by a single gene variant. (n=109)
True	40 (37%)
False	27 (25%)
Don't Know	42 (38%)
