Genetic factors in cephalo facial measurements at birth as revealed by new born-parent correlations.

Father-mother and newborn-parent correlations have been obtained for twelve selected cephalofacial measurements. Newborn-parent correlations were significant for almost all the twelve measurements, indicating a strong genetic component and were of the order 30 to 60 percent of known adult correlations. Role of X-linked factors were indicated for facial and nasal measurements. Maternal factors were influencing almost all the traits. Stepwise multiple regression analysis, involving a total of fifteen independent variables, also revealed similar role of genetic factors.
