[Variability of anthropometric traits in newborn offspring of Russian-Buryat unions]

The variation of 9 anthropometric traits of Buryat, Russian and (Russian x Buryat) F1 hybrid newborns was compared. Data show that hybrid newborns are markedly different either from Buryat or Russian newborns. These differences are associated with significant increase of correlation between 7 anthropometric traits in hybrid newborns. It is suggested that alteration of gene interaction in hybrids is the main reason of observed differences between them and Russian and Buryat newborns.
