The category of institutions is researched in comparison with «genotype» in borders of organizational structure «phenotype» which is formed in evolution as the result of society genotype ancestral attributes interaction and institutional medium conditions. The similarity of institutions to genes and the mechanism of their development, copying, and the ways they influence individuals and organizations are analysed.
