RESUMO
Researches concerning the variation of correlation coefficient (r) in man in relation to four sets of variables were carried out, namely: a set of ten fundamental variables (in which the dependent variable is represented by aging), a set of variational variables (variation ranks of the r), a set of reference variables (r, age, blood pressure, sex and ABO genetic system) and a set of relational variables (relations). This research contributes to the study of multidimensional variational network of the human gerontogenesis (G. Acilugaritei, 1993-1995).

The present paper makes a contribution to the study of the multidimensional variational network of the human gerontogenesis (G. Acalugaritei, 1993-1995). In this respect was rendered evident the variation of the multiple regression coefficient (R) in relation to four sets of variables, as follows: a set of fundamental variables, a set of variational variables (variation ranks of the R), a set of reference variables (R, aging, blood pressure, sex and ABO genetic system) and a set of relational variables (relations).

The object of this paper is to present an original classification of ontogenetic reproduction. The main general criterion used is the degree and type of phylogenetic differentiation. In relation to this criterion, criteria are given for the classification of the fundamental types of ontogenetic reproduction and for the classification of the types of ontogenetic generation cycles. Between the fundamental types of ontogenetic reproduction and the types of ontogenetic generation cycles there is a hierarchical relationship which shows that the former are components of the latter. Between the well-defined types of ontogenetic reproduction there exist many intermediate types.

Individual development in the course of a generation has an unidirectional, irreversible, "closed", predominantly structly-determined, predominantly autoprogrammed, autoreproducible character. The characteristics of individual development differ in terms of its processes, stages, types and orders. Ontogenesis and ageing of the organism represent the principal processes of individual development. Individual development has three main stages (progressive stage, "plateau" stage and regressive stage). The types of individual development may be grouped into two categories: elementary and complex. The complex types result from the combining in different ways of the elementary types. Similarly, orders of the generations of individual development and hierarchical orders of individual development may be differentiated. Between the processes, stages, types and orders of individual development certain "combining" relationships may appear. The processes, stages and types of individual development as well as their mutual relationships serve both development and stability.
