...A.C. Bogle; T. Reed; J.A. Norton, Jr. Asymmetry of a–b ridge count, a dermatoglyphic trait in the second interdigital (ID II) palmar area was studied in 314 identical (MZ) twin-pairs of known placental type. Statistically significant differences were observed for the variability of a-b ridge count...
