    The Zygosity questionnaire asks parents of twin pairs about the resemblance between the twins to determine whether the twin pair is mono- or dizygotic. This questionnaire consists of 10 questions: 6 items about physical similarities between the twin and 4 items about confusion in identifying the twins by parents and others.
