True/False
In a study of concordance, a sample of identical twins was evaluated for adult-onset diabetes. The data below were collected for this trait:
1. In 36 identical twin pairs, both showed adult-onset diabetes.
2. In 40 identical twin pairs, only one showed adult-onset diabetes.
3. In 336 identical twin pairs, neither showed adult-onset diabetes.
Items 1 and 2 can be used to calculate concordance for identical twins as follows: 36/(36 + 40) × 100 = 47%.
