From the Research on Electrophoretical Mobility of Nuclei in Twins

Abstract

I studied 8 pairs of male twins and 14 pairs of female twins. The aim of this paper is to demonstrate the evaluation of development age in pairs of twins examined through the electrophoretical mobility of nuclei. EMN index in pairs of male twins, the index figures do not change dramatically between the ages of 8 – 12. EMN index in pairs of female twins rises from 9 – year – old to 11 – year – old pair. In this paper I want to indicate the studies on development age, which began at The Twins Festival in Szczecin in 1998.
