[Influence of mother's heterozygosity on the variation of anthropometric traits in newborns].
The relationship between mother's heterozygosity as revealed by 14 polymorphic loci and variation of the set of anthropometric traits were studied in normal singleton newborns (174 boys, 127 girls). Statistically significant negative correlation between mother's heterozygosity and the index of fluctuating asymmetry was found in girls. Variances of four traits--body weight, body length, circumference of head and breast measured by first principal component, and mean number of minor deviations from development (stigma) are shown to be minimal in the children born by mothers with the average level of heterozygosity. The groups of newborns with different level of mother's heterozygosity are characterized by different combinations of first principal component, stigma, and the index of fluctuating asymmetry. It is concluded from the whole set of data that children born by mothers with the average level of heterozygosity have the highest level of viability.
