    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.

    Urinary osmolality as measured with density test (specific gravity) using the Atago refractometer PAL-10S BLT/A+W (Atago, Tokyo, Japan). The refractive index is a ratio of the velocity of light in air to the velocity of light in solution, which is directly proportional to the number of dissolved solids in urine.
