[Heterochromatin of the Y-chromosome and variability of human morphophysiological traits]. 1989

S A Nazarenko, and V P Puzyrev, and K T Protasov, and M G Ostrovskaia

80 morpho-physiological traits were studied in a group of 55 men with morphologically identical subtotal deletion of Y chromosome heterochromatin and in a control group of 55 men with normal Y chromosome. No significant differences in mean values of most traits were found between these groups, except for some haematological parameters. With the help of the pattern recognition algorithm, 20 features were extracted which classify the two groups of individuals compared, the recognition error being 4.6%. Electrocardiographic parameters (25% of total traits), some haematological, anthropometric traits and age were included into the pattern recognition system. The results of the study suggest the existence of some modification influence of Y chromosome heterochromatin on the structure of phenotypic relationships between morpho-physiological traits in human ontogenesis.
