Question

Twin,adoption,and family studies show that obesity has a heritability that averages close to ____.
A) 0.1
B) 0.3
C) 0.5
D) 0.7
E) 0.9

Accepted Answer

Twin, adoption, and family studies suggest that genetics plays a significant role in the development of obesity, with heritability estimates averaging around 0.7. This means that genetics contribute to about 70% of the variance in obesity, while environmental factors such as diet and physical activity account for the remaining 30% of the variance. Choice D, 0.7, is the most accurate estimate based on current research.
