In a Study of Concordance, a Sample of Identical Twins

question 14

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.
The concordance for adult-onset diabetes among fraternal twins is 10%. Thus, this trait is not likely to have a strong genetic component.
