Within-pair differences in a-b ridge count asymmetry in monozygotic twins: evidence for a placental proximity effect.

Human heredity - 1 Jan 2000

Bogle A C, Reed T, Norton J A

Abstract excerpt

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 with respect to placentation. Monoch...
