What is the general conclusion of researchers who have investigated the influence of genetic factors on attention-deficit/hyperactivity disorder?
A) The concordance rate for MZ twins is high, however, symptoms appear to be reactions to other mental disorders.
B) The concordance rate among dizygotic twins is higher than for monozygotic twins, suggesting that environmental factors are the most important determinant of this disorder.
C) Genetic factors seem to play no role in the development of this disorder, which is related to rapid alterations in environmental stimulation.
D) Genetic factors substantially contribute to this disorder.
